-Making backups
+    The Paperless-ngx documentation has permanently moved.
 ##############
-Multiple options exist for making backups of your paperless instance,
+    You will be redirected shortly...
 depending on how you installed paperless.
 Before making backups, make sure that paperless is not running.
 Options available to any installation of paperless:
 *   Use the :ref:`document exporter <utilities-exporter>`.
    The document exporter exports all your documents, thumbnails and
    metadata to a specific folder. You may import your documents into a
    fresh instance of paperless again or store your documents in another
    DMS with this export.
 *   The document exporter is also able to update an already existing export.
    Therefore, incremental backups with ``rsync`` are entirely possible.
 .. caution::
    You cannot import the export generated with one version of paperless in a
    different version of paperless. The export contains an exact image of the
    database, and migrations may change the database layout.
 Options available to docker installations:
 *   Backup the docker volumes. These usually reside within
    ``/var/lib/docker/volumes`` on the host and you need to be root in order
    to access them.
    Paperless uses 4 volumes:
    *   ``paperless_media``: This is where your documents are stored.
    *   ``paperless_data``: This is where auxillary data is stored. This
        folder also contains the SQLite database, if you use it.
    *   ``paperless_pgdata``: Exists only if you use PostgreSQL and contains
        the database.
    *   ``paperless_dbdata``: Exists only if you use MariaDB and contains
        the database.
 Options available to bare-metal and non-docker installations:
 *   Backup the entire paperless folder. This ensures that if your paperless instance
    crashes at some point or your disk fails, you can simply copy the folder back
    into place and it works.
    When using PostgreSQL or MariaDB, you'll also have to backup the database.

 Updating Paperless
 ##################
 Docker Route
 ============
 If a new release of paperless-ngx is available, upgrading depends on how you
 installed paperless-ngx in the first place. The releases are available at the
 `release page <https://github.com/paperless-ngx/paperless-ngx/releases>`_.
 First of all, ensure that paperless is stopped.
 .. code:: shell-session
    $ cd /path/to/paperless
    $ docker-compose down
 After that, :ref:`make a backup <administration-backup>`.
 A.  If you pull the image from the docker hub, all you need to do is:
    .. code:: shell-session
        $ docker-compose pull
        $ docker-compose up
    The docker-compose files refer to the ``latest`` version, which is always the latest
    stable release.
 B.  If you built the image yourself, do the following:
    .. code:: shell-session
        $ git pull
        $ docker-compose build
        $ docker-compose up
 Running ``docker-compose up`` will also apply any new database migrations.
 If you see everything working, press CTRL+C once to gracefully stop paperless.
 Then you can start paperless-ngx with ``-d`` to have it run in the background.
    .. note::
        In version 0.9.14, the update process was changed. In 0.9.13 and earlier, the
        docker-compose files specified exact versions and pull won't automatically
        update to newer versions. In order to enable updates as described above, either
        get the new ``docker-compose.yml`` file from `here <https://github.com/paperless-ngx/paperless-ngx/tree/master/docker/compose>`_
        or edit the ``docker-compose.yml`` file, find the line that says
            .. code::
                image: ghcr.io/paperless-ngx/paperless-ngx:0.9.x
        and replace the version with ``latest``:
            .. code::
                image: ghcr.io/paperless-ngx/paperless-ngx:latest
    .. note::
        In version 1.7.1 and onwards, the Docker image can now be pinned to a release series.
        This is often combined with automatic updaters such as Watchtower to allow safer
        unattended upgrading to new bugfix releases only.  It is still recommended to always
        review release notes before upgrading.  To pin your install to a release series, edit
        the ``docker-compose.yml`` find the line that says
            .. code::
                image: ghcr.io/paperless-ngx/paperless-ngx:latest
        and replace the version with the series you want to track, for example:
            .. code::
                image: ghcr.io/paperless-ngx/paperless-ngx:1.7
 Bare Metal Route
 ================
 After grabbing the new release and unpacking the contents, do the following:
 1.  Update dependencies. New paperless version may require additional
    dependencies. The dependencies required are listed in the section about
    :ref:`bare metal installations <setup-bare_metal>`.
 2.  Update python requirements. Keep in mind to activate your virtual environment
    before that, if you use one.
    .. code:: shell-session
        $ pip install -r requirements.txt
 3.  Migrate the database.
    .. code:: shell-session
        $ cd src
        $ python3 manage.py migrate
    This might not actually do anything. Not every new paperless version comes with new
    database migrations.
 Downgrading Paperless
 #####################
 Downgrades are possible. However, some updates also contain database migrations (these change the layout of the database and may move data).
 In order to move back from a version that applied database migrations, you'll have to revert the database migration *before* downgrading,
 and then downgrade paperless.
 This table lists the compatible versions for each database migration number.
 +------------------+-----------------+
 | Migration number | Version range   |
 +------------------+-----------------+
 | 1011             | 1.0.0           |
 +------------------+-----------------+
 | 1012             | 1.1.0 - 1.2.1   |
 +------------------+-----------------+
 | 1014             | 1.3.0 - 1.3.1   |
 +------------------+-----------------+
 | 1016             | 1.3.2 - current |
 +------------------+-----------------+
 Execute the following management command to migrate your database:
 .. code:: shell-session
    $ python3 manage.py migrate documents <migration number>
 .. note::
    Some migrations cannot be undone. The command will issue errors if that happens.
 .. _utilities-management-commands:
 Management utilities
 ####################
 Paperless comes with some management commands that perform various maintenance
 tasks on your paperless instance. You can invoke these commands in the following way:
 With docker-compose, while paperless is running:
 .. code:: shell-session
    $ cd /path/to/paperless
    $ docker-compose exec webserver <command> <arguments>
 With docker, while paperless is running:
 .. code:: shell-session
    $ docker exec -it <container-name> <command> <arguments>
 Bare metal:
 .. code:: shell-session
    $ cd /path/to/paperless/src
    $ python3 manage.py <command> <arguments>
 All commands have built-in help, which can be accessed by executing them with
 the argument ``--help``.
 .. _utilities-exporter:
 Document exporter
 =================
 The document exporter exports all your data from paperless into a folder for
 backup or migration to another DMS.
 If you use the document exporter within a cronjob to backup your data you might use the ``-T`` flag behind exec to suppress "The input device is not a TTY" errors. For example: ``docker-compose exec -T webserver document_exporter ../export``
 .. code::
    document_exporter target [-c] [-f] [-d]
    optional arguments:
    -c, --compare-checksums
    -f, --use-filename-format
    -d, --delete
 ``target`` is a folder to which the data gets written. This includes documents,
 thumbnails and a ``manifest.json`` file. The manifest contains all metadata from
 the database (correspondents, tags, etc).
 When you use the provided docker compose script, specify ``../export`` as the
 target. This path inside the container is automatically mounted on your host on
 the folder ``export``.
 If the target directory already exists and contains files, paperless will assume
 that the contents of the export directory are a previous export and will attempt
 to update the previous export. Paperless will only export changed and added files.
 Paperless determines whether a file has changed by inspecting the file attributes
 "date/time modified" and "size". If that does not work out for you, specify
 ``--compare-checksums`` and paperless will attempt to compare file checksums instead.
 This is slower.
 Paperless will not remove any existing files in the export directory. If you want
 paperless to also remove files that do not belong to the current export such as files
 from deleted documents, specify ``--delete``. Be careful when pointing paperless to
 a directory that already contains other files.
 The filenames generated by this command follow the format
 ``[date created] [correspondent] [title].[extension]``.
 If you want paperless to use ``PAPERLESS_FILENAME_FORMAT`` for exported filenames
 instead, specify ``--use-filename-format``.
 .. _utilities-importer:
 Document importer
 =================
 The document importer takes the export produced by the `Document exporter`_ and
 imports it into paperless.
 The importer works just like the exporter.  You point it at a directory, and
 the script does the rest of the work:
 .. code::
    document_importer source
 When you use the provided docker compose script, put the export inside the
 ``export`` folder in your paperless source directory. Specify ``../export``
 as the ``source``.
 .. note::
    Importing from a previous version of Paperless may work, but for best results
    it is suggested to match the versions.
 .. _utilities-retagger:
 Document retagger
 =================
 Say you've imported a few hundred documents and now want to introduce
 a tag or set up a new correspondent, and apply its matching to all of
 the currently-imported docs. This problem is common enough that
 there are tools for it.
 .. code::
    document_retagger [-h] [-c] [-T] [-t] [-i] [--use-first] [-f]
    optional arguments:
    -c, --correspondent
    -T, --tags
    -t, --document_type
    -s, --storage_path
    -i, --inbox-only
    --use-first
    -f, --overwrite
 Run this after changing or adding matching rules. It'll loop over all
 of the documents in your database and attempt to match documents
 according to the new rules.
 Specify any combination of ``-c``, ``-T``, ``-t`` and ``-s`` to have the
 retagger perform matching of the specified metadata type. If you don't
 specify any of these options, the document retagger won't do anything.
 Specify ``-i`` to have the document retagger work on documents tagged
 with inbox tags only. This is useful when you don't want to mess with
 your already processed documents.
 When multiple document types or correspondents match a single document,
 the retagger won't assign these to the document. Specify ``--use-first``
 to override this behavior and just use the first correspondent or type
 it finds. This option does not apply to tags, since any amount of tags
 can be applied to a document.
 Finally, ``-f`` specifies that you wish to overwrite already assigned
 correspondents, types and/or tags. The default behavior is to not
 assign correspondents and types to documents that have this data already
 assigned. ``-f`` works differently for tags: By default, only additional tags get
 added to documents, no tags will be removed. With ``-f``, tags that don't
 match a document anymore get removed as well.
 Managing the Automatic matching algorithm
 =========================================
 The *Auto* matching algorithm requires a trained neural network to work.
 This network needs to be updated whenever somethings in your data
 changes. The docker image takes care of that automatically with the task
 scheduler. You can manually renew the classifier by invoking the following
 management command:
 .. code::
    document_create_classifier
 This command takes no arguments.
 .. _`administration-index`:
 Managing the document search index
 ==================================
 The document search index is responsible for delivering search results for the
 website. The document index is automatically updated whenever documents get
 added to, changed, or removed from paperless. However, if the search yields
 non-existing documents or won't find anything, you may need to recreate the
 index manually.
 .. code::
    document_index {reindex,optimize}
 Specify ``reindex`` to have the index created from scratch. This may take some
 time.
 Specify ``optimize`` to optimize the index. This updates certain aspects of
 the index and usually makes queries faster and also ensures that the
 autocompletion works properly. This command is regularly invoked by the task
 scheduler.
 .. _utilities-renamer:
 Managing filenames
 ==================
 If you use paperless' feature to
 :ref:`assign custom filenames to your documents <advanced-file_name_handling>`,
 you can use this command to move all your files after changing
 the naming scheme.
 .. warning::
    Since this command moves your documents, it is advised to do
    a backup beforehand. The renaming logic is robust and will never overwrite
    or delete a file, but you can't ever be careful enough.
 .. code::
    document_renamer
 The command takes no arguments and processes all your documents at once.
 Learn how to use :ref:`Management Utilities<utilities-management-commands>`.
 .. _utilities-sanity-checker:
 Sanity checker
 ==============
 Paperless has a built-in sanity checker that inspects your document collection for issues.
 The issues detected by the sanity checker are as follows:
 * Missing original files.
 * Missing archive files.
 * Inaccessible original files due to improper permissions.
 * Inaccessible archive files due to improper permissions.
 * Corrupted original documents by comparing their checksum against what is stored in the database.
 * Corrupted archive documents by comparing their checksum against what is stored in the database.
 * Missing thumbnails.
 * Inaccessible thumbnails due to improper permissions.
 * Documents without any content (warning).
 * Orphaned files in the media directory (warning). These are files that are not referenced by any document im paperless.
 .. code::
    document_sanity_checker
 The command takes no arguments. Depending on the size of your document archive, this may take some time.
 Fetching e-mail
 ===============
 Paperless automatically fetches your e-mail every 10 minutes by default. If
 you want to invoke the email consumer manually, call the following management
 command:
 .. code::
    mail_fetcher
 The command takes no arguments and processes all your mail accounts and rules.
 .. note::
    As of October 2022 Microsoft no longer supports IMAP authentication for Exchange
    servers, thus Exchange is no longer supported until a solution is implemented in
    the Python IMAP library used by Paperless. See  `learn.microsoft.com`_
 .. _learn.microsoft.com: https://learn.microsoft.com/en-us/exchange/clients-and-mobile-in-exchange-online/deprecation-of-basic-authentication-exchange-online
 .. _utilities-archiver:
 Creating archived documents
 ===========================
 Paperless stores archived PDF/A documents alongside your original documents.
 These archived documents will also contain selectable text for image-only
 originals.
 These documents are derived from the originals, which are always stored
 unmodified. If coming from an earlier version of paperless, your documents
 won't have archived versions.
 This command creates PDF/A documents for your documents.
 .. code::
    document_archiver --overwrite --document <id>
 This command will only attempt to create archived documents when no archived
 document exists yet, unless ``--overwrite`` is specified. If ``--document <id>``
 is specified, the archiver will only process that document.
 .. note::
    This command essentially performs OCR on all your documents again,
    according to your settings. If you run this with ``PAPERLESS_OCR_MODE=redo``,
    it will potentially run for a very long time. You can cancel the command
    at any time, since this command will skip already archived versions the next time
    it is run.
 .. note::
    Some documents will cause errors and cannot be converted into PDF/A documents,
    such as encrypted PDF documents. The archiver will skip over these documents
    each time it sees them.
 .. _utilities-encyption:
 Managing encryption
 ===================
 Documents can be stored in Paperless using GnuPG encryption.
 .. danger::
    Encryption is deprecated since paperless-ngx 0.9 and doesn't really provide any
    additional security, since you have to store the passphrase in a configuration
    file on the same system as the encrypted documents for paperless to work.
    Furthermore, the entire text content of the documents is stored plain in the
    database, even if your documents are encrypted. Filenames are not encrypted as
    well.
    Also, the web server provides transparent access to your encrypted documents.
    Consider running paperless on an encrypted filesystem instead, which will then
    at least provide security against physical hardware theft.
 Enabling encryption
 -------------------
 Enabling encryption is no longer supported.
 Disabling encryption
 --------------------
 Basic usage to disable encryption of your document store:
 (Note: If ``PAPERLESS_PASSPHRASE`` isn't set already, you need to specify it here)
 .. code::

 ################################################################
 Paperless will compare the matching algorithms defined by every tag, correspondent,
 document type, and storage path in your database to see if they apply to the text
 in a document. In other words, if you define a tag called ``Home Utility``
 that had a ``match`` property of ``bc hydro`` and a ``matching_algorithm`` of
 ``literal``, Paperless will automatically tag your newly-consumed document with
 your ``Home Utility`` tag so long as the text ``bc hydro`` appears in the body
 of the document somewhere.
 The matching logic is quite powerful. It supports searching the text of your
 document with different algorithms, and as such, some experimentation may be
 necessary to get things right.
 In order to have a tag, correspondent, document type, or storage path assigned
 automatically to newly consumed documents, assign a match and matching algorithm
 using the web interface. These settings define when to assign tags, correspondents,
 document types, and storage paths to documents.
 The following algorithms are available:
 * **Any:** Looks for any occurrence of any word provided in match in the PDF.
  If you define the match as ``Bank1 Bank2``, it will match documents containing
  either of these terms.
 * **All:** Requires that every word provided appears in the PDF, albeit not in the
  order provided.
 * **Literal:** Matches only if the match appears exactly as provided (i.e. preserve ordering) in the PDF.
 * **Regular expression:** Parses the match as a regular expression and tries to
  find a match within the document.
 * **Fuzzy match:** I don't know. Look at the source.
 * **Auto:** Tries to automatically match new documents. This does not require you
  to set a match. See the notes below.
 When using the *any* or *all* matching algorithms, you can search for terms
 that consist of multiple words by enclosing them in double quotes. For example,
 defining a match text of ``"Bank of America" BofA`` using the *any* algorithm,
 will match documents that contain either "Bank of America" or "BofA", but will
 not match documents containing "Bank of South America".
 Then just save your tag, correspondent, document type, or storage path and run
 another document through the consumer.  Once complete, you should see the
 newly-created document, automatically tagged with the appropriate data.
 .. _advanced-automatic_matching:
 Automatic matching
 ==================
 Paperless-ngx comes with a new matching algorithm called *Auto*. This matching
 algorithm tries to assign tags, correspondents, document types, and storage paths
 to your documents based on how you have already assigned these on existing documents.
 It uses a neural network under the hood.
 If, for example, all your bank statements of your account 123 at the Bank of
 America are tagged with the tag "bofa_123" and the matching algorithm of this
 tag is set to *Auto*, this neural network will examine your documents and
 automatically learn when to assign this tag.
 Paperless tries to hide much of the involved complexity with this approach.
 However, there are a couple caveats you need to keep in mind when using this
 feature:
 * Changes to your documents are not immediately reflected by the matching
  algorithm. The neural network needs to be *trained* on your documents after
  changes. Paperless periodically (default: once each hour) checks for changes
  and does this automatically for you.
 * The Auto matching algorithm only takes documents into account which are NOT
  placed in your inbox (i.e. have any inbox tags assigned to them). This ensures
  that the neural network only learns from documents which you have correctly
  tagged before.
 * The matching algorithm can only work if there is a correlation between the
  tag, correspondent, document type, or storage path and the document itself.
  Your bank statements usually contain your bank account number and the name
  of the bank, so this works reasonably well, However, tags such as "TODO"
  cannot be automatically assigned.
 * The matching algorithm needs a reasonable number of documents to identify when
  to assign tags, correspondents, storage paths, and types. If one out of a
  thousand documents has the correspondent "Very obscure web shop I bought
  something five years ago", it will probably not assign this correspondent
  automatically if you buy something from them again. The more documents, the better.
 * Paperless also needs a reasonable amount of negative examples to decide when
  not to assign a certain tag, correspondent, document type, or storage path. This will
  usually be the case as you start filling up paperless with documents.
  Example: If all your documents are either from "Webshop" and "Bank", paperless
  will assign one of these correspondents to ANY new document, if both are set
  to automatic matching.
 Hooking into the consumption process
 ####################################
 Sometimes you may want to do something arbitrary whenever a document is
 consumed.  Rather than try to predict what you may want to do, Paperless lets
 you execute scripts of your own choosing just before or after a document is
 consumed using a couple simple hooks.
 Just write a script, put it somewhere that Paperless can read & execute, and
 then put the path to that script in ``paperless.conf`` or ``docker-compose.env`` with the variable name
 of either ``PAPERLESS_PRE_CONSUME_SCRIPT`` or
 ``PAPERLESS_POST_CONSUME_SCRIPT``.
 .. important::
    These scripts are executed in a **blocking** process, which means that if
    a script takes a long time to run, it can significantly slow down your
    document consumption flow.  If you want things to run asynchronously,
    you'll have to fork the process in your script and exit.
 Pre-consumption script
 ======================
 Executed after the consumer sees a new document in the consumption folder, but
 before any processing of the document is performed. This script can access the
 following relevant environment variables set:
 * ``DOCUMENT_SOURCE_PATH``
 A simple but common example for this would be creating a simple script like
 this:
 ``/usr/local/bin/ocr-pdf``
 .. code:: bash
    #!/usr/bin/env bash
    pdf2pdfocr.py -i ${DOCUMENT_SOURCE_PATH}
 ``/etc/paperless.conf``
 .. code:: bash
    ...
    PAPERLESS_PRE_CONSUME_SCRIPT="/usr/local/bin/ocr-pdf"
    ...
 This will pass the path to the document about to be consumed to ``/usr/local/bin/ocr-pdf``,
 which will in turn call `pdf2pdfocr.py`_ on your document, which will then
 overwrite the file with an OCR'd version of the file and exit.  At which point,
 the consumption process will begin with the newly modified file.
 The script's stdout and stderr will be logged line by line to the webserver log, along
 with the exit code of the script.
 .. _pdf2pdfocr.py: https://github.com/LeoFCardoso/pdf2pdfocr
 .. _advanced-post_consume_script:
 Post-consumption script
 =======================
 Executed after the consumer has successfully processed a document and has moved it
 into paperless. It receives the following environment variables:
 * ``DOCUMENT_ID``
 * ``DOCUMENT_FILE_NAME``
 * ``DOCUMENT_CREATED``
 * ``DOCUMENT_MODIFIED``
 * ``DOCUMENT_ADDED``
 * ``DOCUMENT_SOURCE_PATH``
 * ``DOCUMENT_ARCHIVE_PATH``
 * ``DOCUMENT_THUMBNAIL_PATH``
 * ``DOCUMENT_DOWNLOAD_URL``
 * ``DOCUMENT_THUMBNAIL_URL``
 * ``DOCUMENT_CORRESPONDENT``
 * ``DOCUMENT_TAGS``
 * ``DOCUMENT_ORIGINAL_FILENAME``
 The script can be in any language, but for a simple shell script
 example, you can take a look at `post-consumption-example.sh`_ in this project.
 The post consumption script cannot cancel the consumption process.
 The script's stdout and stderr will be logged line by line to the webserver log, along
 with the exit code of the script.
 Docker
 ------
 Assumed you have ``/home/foo/paperless-ngx/scripts/post-consumption-example.sh``.
 You can pass that script into the consumer container via a host mount in your ``docker-compose.yml``.
 .. code:: bash
  ...
  consumer:
    ...
    volumes:
      ...
      - /home/paperless-ngx/scripts:/path/in/container/scripts/
  ...
 Example (docker-compose.yml): ``- /home/foo/paperless-ngx/scripts:/usr/src/paperless/scripts``
 which in turn requires the variable ``PAPERLESS_POST_CONSUME_SCRIPT`` in ``docker-compose.env``  to point to ``/path/in/container/scripts/post-consumption-example.sh``.
 Example (docker-compose.env): ``PAPERLESS_POST_CONSUME_SCRIPT=/usr/src/paperless/scripts/post-consumption-example.sh``
 Troubleshooting:
 - Monitor the docker-compose log ``cd ~/paperless-ngx; docker-compose logs -f``
 - Check your script's permission e.g. in case of permission error ``sudo chmod 755 post-consumption-example.sh``
 - Pipe your scripts's output to a log file e.g. ``echo "${DOCUMENT_ID}" | tee --append /usr/src/paperless/scripts/post-consumption-example.log``

 File name handling
 ##################
 By default, paperless stores your documents in the media directory and renames them
 using the identifier which it has assigned to each document. You will end up getting
 files like ``0000123.pdf`` in your media directory. This isn't necessarily a bad
 thing, because you normally don't have to access these files manually. However, if
 you wish to name your files differently, you can do that by adjusting the
 ``PAPERLESS_FILENAME_FORMAT`` configuration option. Paperless adds the correct
 file extension e.g. ``.pdf``, ``.jpg`` automatically.
 This variable allows you to configure the filename (folders are allowed) using
 placeholders. For example, configuring this to
 .. code:: bash
    PAPERLESS_FILENAME_FORMAT={created_year}/{correspondent}/{title}
 will create a directory structure as follows:
 .. code::
    2019/
      My bank/
        Statement January.pdf
        Statement February.pdf
    2020/
      My bank/
        Statement January.pdf
        Letter.pdf
        Letter_01.pdf
      Shoe store/
        My new shoes.pdf
 .. danger::
    Do not manually move your files in the media folder. Paperless remembers the
    last filename a document was stored as. If you do rename a file, paperless will
    report your files as missing and won't be able to find them.
 Paperless provides the following placeholders within filenames:
 * ``{asn}``: The archive serial number of the document, or "none".
 * ``{correspondent}``: The name of the correspondent, or "none".
 * ``{document_type}``: The name of the document type, or "none".
 * ``{tag_list}``: A comma separated list of all tags assigned to the document.
 * ``{title}``: The title of the document.
 * ``{created}``: The full date (ISO format) the document was created.
 * ``{created_year}``: Year created only, formatted as the year with century.
 * ``{created_year_short}``: Year created only, formatted as the year without century, zero padded.
 * ``{created_month}``: Month created only (number 01-12).
 * ``{created_month_name}``: Month created name, as per locale
 * ``{created_month_name_short}``: Month created abbreviated name, as per locale
 * ``{created_day}``: Day created only (number 01-31).
 * ``{added}``: The full date (ISO format) the document was added to paperless.
 * ``{added_year}``: Year added only.
 * ``{added_year_short}``: Year added only, formatted as the year without century, zero padded.
 * ``{added_month}``: Month added only (number 01-12).
 * ``{added_month_name}``: Month added name, as per locale
 * ``{added_month_name_short}``: Month added abbreviated name, as per locale
 * ``{added_day}``: Day added only (number 01-31).
 Paperless will try to conserve the information from your database as much as possible.
 However, some characters that you can use in document titles and correspondent names (such
 as ``: \ /`` and a couple more) are not allowed in filenames and will be replaced with dashes.
 If paperless detects that two documents share the same filename, paperless will automatically
 append ``_01``, ``_02``, etc to the filename. This happens if all the placeholders in a filename
 evaluate to the same value.
 .. hint::
    You can affect how empty placeholders are treated by changing the following setting to
    `true`.
    .. code::
        PAPERLESS_FILENAME_FORMAT_REMOVE_NONE=True
    Doing this results in all empty placeholders resolving to "" instead of "none" as stated above.
    Spaces before empty placeholders are removed as well, empty directories are omitted.
 .. hint::
    Paperless checks the filename of a document whenever it is saved. Therefore,
    you need to update the filenames of your documents and move them after altering
    this setting by invoking the :ref:`document renamer <utilities-renamer>`.
 .. warning::
    Make absolutely sure you get the spelling of the placeholders right, or else
    paperless will use the default naming scheme instead.
 .. caution::
    As of now, you could totally tell paperless to store your files anywhere outside
    the media directory by setting
    .. code::
        PAPERLESS_FILENAME_FORMAT=../../my/custom/location/{title}
    However, keep in mind that inside docker, if files get stored outside of the
    predefined volumes, they will be lost after a restart of paperless.
 Storage paths
 #############
 One of the best things in Paperless is that you can not only access the documents via the
 web interface, but also via the file system.
 When as single storage layout is not sufficient for your use case, storage paths come to
 the rescue. Storage paths allow you to configure more precisely where each document is stored
 in the file system.
 - Each storage path is a `PAPERLESS_FILENAME_FORMAT` and follows the rules described above
 - Each document is assigned a storage path using the matching algorithms described above, but
  can be overwritten at any time
 For example, you could define the following two storage paths:
 1. Normal communications are put into a folder structure sorted by `year/correspondent`
 2. Communications with insurance companies are stored in a flat structure with longer file names,
   but containing the full date of the correspondence.
 .. code::
    By Year = {created_year}/{correspondent}/{title}
    Insurances = Insurances/{correspondent}/{created_year}-{created_month}-{created_day} {title}
 If you then map these storage paths to the documents, you might get the following result.
 For simplicity, `By Year` defines the same structure as in the previous example above.
 .. code:: text
   2019/                                   # By Year
      My bank/
        Statement January.pdf
        Statement February.pdf
    Insurances/                           # Insurances
      Healthcare 123/
        2022-01-01 Statement January.pdf
        2022-02-02 Letter.pdf
        2022-02-03 Letter.pdf
      Dental 456/
        2021-12-01 New Conditions.pdf
 .. hint::
    Defining a storage path is optional. If no storage path is defined for a document, the global
    `PAPERLESS_FILENAME_FORMAT` is applied.
 .. caution::
    If you adjust the format of an existing storage path, old documents don't get relocated automatically.
    You need to run the :ref:`document renamer <utilities-renamer>` to adjust their pathes.
 .. _advanced-celery-monitoring:
 Celery Monitoring
 #################
 The monitoring tool `Flower <https://flower.readthedocs.io/en/latest/index.html>`_ can be used to view more
 detailed information about the health of the celery workers used for asynchronous tasks.  This includes details
 on currently running, queued and completed tasks, timing and more.  Flower can also be used with Prometheus, as it
 exports metrics.  For details on its capabilities, refer to the Flower documentation.
 To configure Flower further, create a `flowerconfig.py` and place it into the `src/paperless` directory.  For
 a Docker installation, you can use volumes to accomplish this:
 .. code:: yaml
    services:
      # ...
      webserver:
        # ...
        volumes:
          - /path/to/my/flowerconfig.py:/usr/src/paperless/src/paperless/flowerconfig.py:ro
 Custom Container Initialization
 ###############################
 The Docker image includes the ability to run custom user scripts during startup.  This could be
 utilized for installing additional tools or Python packages, for example.
 To utilize this, mount a folder containing your scripts to the custom initialization directory, `/custom-cont-init.d`
 and place scripts you wish to run inside.  For security, the folder and its contents must be owned by `root`.
 Additionally, scripts must only be writable by `root`.
 Your scripts will be run directly before the webserver completes startup.  Scripts will be run by the `root` user.
 This is an advanced functionality with which you could break functionality or lose data.
 For example, using Docker Compose:
 .. code:: yaml
    services:
      # ...
      webserver:
        # ...
        volumes:
          - /path/to/my/scripts:/custom-cont-init.d:ro
 .. _advanced-mysql-caveats:
 MySQL Caveats
 #############
 Case Sensitivity
 ================
 The database interface does not provide a method to configure a MySQL database to
 be case sensitive.  This would prevent a user from creating a tag ``Name`` and ``NAME``
 as they are considered the same.
 Per Django documentation, to enable this requires manual intervention.  To enable
 case sensetive tables, you can execute the following command against each table:
 ``ALTER TABLE <table_name> CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_bin;``
 You can also set the default for new tables (this does NOT affect existing tables) with:
 ``ALTER DATABASE <db_name> CHARACTER SET utf8mb4 COLLATE utf8mb4_bin;``

 ************
 The REST API
 ************
-Paperless makes use of the `Django REST Framework`_ standard API interface.
+.. cssclass:: redirect-notice
 It provides a browsable API for most of its endpoints, which you can inspect
 at ``http://<paperless-host>:<port>/api/``. This also documents most of the
 available filters and ordering fields.
-.. _Django REST Framework: http://django-rest-framework.org/
+    The Paperless-ngx documentation has permanently moved.
-The API provides 5 main endpoints:
+    You will be redirected shortly...
 *   ``/api/documents/``: Full CRUD support, except POSTing new documents. See below.
 *   ``/api/correspondents/``: Full CRUD support.
 *   ``/api/document_types/``: Full CRUD support.
 *   ``/api/logs/``: Read-Only.
 *   ``/api/tags/``: Full CRUD support.
 All of these endpoints except for the logging endpoint
 allow you to fetch, edit and delete individual objects
 by appending their primary key to the path, for example ``/api/documents/454/``.
 The objects served by the document endpoint contain the following fields:
 *   ``id``: ID of the document. Read-only.
 *   ``title``: Title of the document.
 *   ``content``: Plain text content of the document.
 *   ``tags``: List of IDs of tags assigned to this document, or empty list.
 *   ``document_type``: Document type of this document, or null.
 *   ``correspondent``:  Correspondent of this document or null.
 *   ``created``: The date time at which this document was created.
 *   ``created_date``: The date (YYYY-MM-DD) at which this document was created. Optional. If also passed with created, this is ignored.
 *   ``modified``: The date at which this document was last edited in paperless. Read-only.
 *   ``added``: The date at which this document was added to paperless. Read-only.
 *   ``archive_serial_number``: The identifier of this document in a physical document archive.
 *   ``original_file_name``: Verbose filename of the original document. Read-only.
 *   ``archived_file_name``: Verbose filename of the archived document. Read-only. Null if no archived document is available.
 Downloading documents
 #####################
 In addition to that, the document endpoint offers these additional actions on
 individual documents:
 *   ``/api/documents/<pk>/download/``: Download the document.
 *   ``/api/documents/<pk>/preview/``: Display the document inline,
    without downloading it.
 *   ``/api/documents/<pk>/thumb/``: Download the PNG thumbnail of a document.
 Paperless generates archived PDF/A documents from consumed files and stores both
 the original files as well as the archived files. By default, the endpoints
 for previews and downloads serve the archived file, if it is available.
 Otherwise, the original file is served.
 Some document cannot be archived.
 The endpoints correctly serve the response header fields ``Content-Disposition``
 and ``Content-Type`` to indicate the filename for download and the type of content of
 the document.
 In order to download or preview the original document when an archived document is available,
 supply the query parameter ``original=true``.
 .. hint::
    Paperless used to provide these functionality at ``/fetch/<pk>/preview``,
    ``/fetch/<pk>/thumb`` and ``/fetch/<pk>/doc``. Redirects to the new URLs
    are in place. However, if you use these old URLs to access documents, you
    should update your app or script to use the new URLs.
 Getting document metadata
 #########################
 The api also has an endpoint to retrieve read-only metadata about specific documents. this
 information is not served along with the document objects, since it requires reading
 files and would therefore slow down document lists considerably.
 Access the metadata of a document with an ID ``id`` at ``/api/documents/<id>/metadata/``.
 The endpoint reports the following data:
 *   ``original_checksum``: MD5 checksum of the original document.
 *   ``original_size``: Size of the original document, in bytes.
 *   ``original_mime_type``: Mime type of the original document.
 *   ``media_filename``: Current filename of the document, under which it is stored inside the media directory.
 *   ``has_archive_version``: True, if this document is archived, false otherwise.
 *   ``original_metadata``: A list of metadata associated with the original document. See below.
 *   ``archive_checksum``: MD5 checksum of the archived document, or null.
 *   ``archive_size``: Size of the archived document in bytes, or null.
 *   ``archive_metadata``: Metadata associated with the archived document, or null. See below.
 File metadata is reported as a list of objects in the following form:
 .. code:: json
    [
        {
            "namespace": "http://ns.adobe.com/pdf/1.3/",
            "prefix": "pdf",
            "key": "Producer",
            "value": "SparklePDF, Fancy edition"
        },
    ]
 ``namespace`` and ``prefix`` can be null. The actual metadata reported depends on the file type and the metadata
 available in that specific document. Paperless only reports PDF metadata at this point.
 Authorization
 #############
 The REST api provides three different forms of authentication.
 1.  Basic authentication
    Authorize by providing a HTTP header in the form
    .. code::
        Authorization: Basic <credentials>
    where ``credentials`` is a base64-encoded string of ``<username>:<password>``
 2.  Session authentication
    When you're logged into paperless in your browser, you're automatically
    logged into the API as well and don't need to provide any authorization
    headers.
 3.  Token authentication
    Paperless also offers an endpoint to acquire authentication tokens.
    POST a username and password as a form or json string to ``/api/token/``
    and paperless will respond with a token, if the login data is correct.
    This token can be used to authenticate other requests with the
    following HTTP header:
    .. code::
        Authorization: Token <token>
    Tokens can be managed and revoked in the paperless admin.
 Searching for documents
 #######################
 Full text searching is available on the ``/api/documents/`` endpoint. Two specific
 query parameters cause the API to return full text search results:
 *   ``/api/documents/?query=your%20search%20query``: Search for a document using a full text query.
    For details on the syntax, see :ref:`basic-usage_searching`.
 *   ``/api/documents/?more_like=1234``: Search for documents similar to the document with id 1234.
 Pagination works exactly the same as it does for normal requests on this endpoint.
 Certain limitations apply to full text queries:
 *   Results are always sorted by search score. The results matching the query best will show up first.
 *   Only a small subset of filtering parameters are supported.
 Furthermore, each returned document has an additional ``__search_hit__`` attribute with various information
 about the search results:
 .. code::
    {
        "count": 31,
        "next": "http://localhost:8000/api/documents/?page=2&query=test",
        "previous": null,
        "results": [
            ...
            {
                "id": 123,
                "title": "title",
                "content": "content",
                ...
                "__search_hit__": {
                    "score": 0.343,
                    "highlights": "text <span class=\"match\">Test</span> text",
                    "rank": 23
                }
            },
            ...
        ]
    }
 *   ``score`` is an indication how well this document matches the query relative to the other search results.
 *   ``highlights`` is an excerpt from the document content and highlights the search terms with ``<span>`` tags as shown above.
 *   ``rank`` is the index of the search results. The first result will have rank 0.
 ``/api/search/autocomplete/``
 =============================
 Get auto completions for a partial search term.
 Query parameters:
 *   ``term``: The incomplete term.
 *   ``limit``: Amount of results. Defaults to 10.
 Results returned by the endpoint are ordered by importance of the term in the
 document index. The first result is the term that has the highest Tf/Idf score
 in the index.
 .. code:: json
    [
        "term1",
        "term3",
        "term6",
        "term4"
    ]
 .. _api-file_uploads:
 POSTing documents
 #################
 The API provides a special endpoint for file uploads:
 ``/api/documents/post_document/``
 POST a multipart form to this endpoint, where the form field ``document`` contains
 the document that you want to upload to paperless. The filename is sanitized and
 then used to store the document in a temporary directory, and the consumer will
 be instructed to consume the document from there.
 The endpoint supports the following optional form fields:
 *   ``title``: Specify a title that the consumer should use for the document.
 *   ``created``: Specify a DateTime where the document was created (e.g. "2016-04-19" or "2016-04-19 06:15:00+02:00").
 *   ``correspondent``: Specify the ID of a correspondent that the consumer should use for the document.
 *   ``document_type``: Similar to correspondent.
 *   ``tags``: Similar to correspondent. Specify this multiple times to have multiple tags added
    to the document.
 The endpoint will immediately return "OK" if the document consumption process
 was started successfully. No additional status information about the consumption
 process itself is available, since that happens in a different process.
 .. _api-versioning:
 API Versioning
 ##############
 The REST API is versioned since Paperless-ngx 1.3.0.
 * Versioning ensures that changes to the API don't break older clients.
 * Clients specify the specific version of the API they wish to use with every request and Paperless will handle the request using the specified API version.
 * Even if the underlying data model changes, older API versions will always serve compatible data.
 * If no version is specified, Paperless will serve version 1 to ensure compatibility with older clients that do not request a specific API version.
 API versions are specified by submitting an additional HTTP ``Accept`` header with every request:
 .. code::
    Accept: application/json; version=6
 If an invalid version is specified, Paperless 1.3.0 will respond with "406 Not Acceptable" and an error message in the body.
 Earlier versions of Paperless will serve API version 1 regardless of whether a version is specified via the ``Accept`` header.
 If a client wishes to verify whether it is compatible with any given server, the following procedure should be performed:
 1.  Perform an *authenticated* request against any API endpoint. If the server is on version 1.3.0 or newer, the server will
    add two custom headers to the response:
    .. code::
        X-Api-Version: 2
        X-Version: 1.3.0
 2.  Determine whether the client is compatible with this server based on the presence/absence of these headers and their values if present.
 API Changelog
 =============
 Version 1
 ---------
 Initial API version.
 Version 2
 ---------
 * Added field ``Tag.color``. This read/write string field contains a hex color such as ``#a6cee3``.
 * Added read-only field ``Tag.text_color``. This field contains the text color to use for a specific tag, which is either black or white depending on the brightness of ``Tag.color``.
 * Removed field ``Tag.colour``.

 Required services
 #################
 PAPERLESS_REDIS=<url>
    This is required for processing scheduled tasks such as email fetching, index
    optimization and for training the automatic document matcher.
    * If your Redis server needs login credentials PAPERLESS_REDIS = ``redis://<username>:<password>@<host>:<port>``
    * With the requirepass option PAPERLESS_REDIS = ``redis://:<password>@<host>:<port>``
    `More information on securing your Redis Instance <https://redis.io/docs/getting-started/#securing-redis>`_.
    Defaults to redis://localhost:6379.
 PAPERLESS_DBENGINE=<engine_name>
    Optional, gives the ability to choose Postgres or MariaDB for database engine.
    Available options are `postgresql` and `mariadb`.
    Default is `postgresql`.
    .. warning::
      Using MariaDB comes with some caveats.  See :ref:`advanced-mysql-caveats` for details.
 PAPERLESS_DBHOST=<hostname>
    By default, sqlite is used as the database backend. This can be changed here.
    Set PAPERLESS_DBHOST and another database will be used instead of sqlite.
 PAPERLESS_DBPORT=<port>
    Adjust port if necessary.
    Default is 5432.
 PAPERLESS_DBNAME=<name>
    Database name in PostgreSQL or MariaDB.
    Defaults to "paperless".
 PAPERLESS_DBUSER=<name>
    Database user in PostgreSQL or MariaDB.
    Defaults to "paperless".
 PAPERLESS_DBPASS=<password>
    Database password for PostgreSQL or MariaDB.
    Defaults to "paperless".
 PAPERLESS_DBSSLMODE=<mode>
    SSL mode to use when connecting to PostgreSQL.
    See `the official documentation about sslmode <https://www.postgresql.org/docs/current/libpq-ssl.html>`_.
    Default is ``prefer``.
 PAPERLESS_DB_TIMEOUT=<float>
    Amount of time for a database connection to wait for the database to unlock.
    Mostly applicable for an sqlite based installation, consider changing to postgresql
    if you need to increase this.
    Defaults to unset, keeping the Django defaults.
 Paths and folders
 #################
 PAPERLESS_CONSUMPTION_DIR=<path>
    This where your documents should go to be consumed.  Make sure that it exists
    and that the user running the paperless service can read/write its contents
    before you start Paperless.
    Don't change this when using docker, as it only changes the path within the
    container. Change the local consumption directory in the docker-compose.yml
    file instead.
    Defaults to "../consume/", relative to the "src" directory.
 PAPERLESS_DATA_DIR=<path>
    This is where paperless stores all its data (search index, SQLite database,
    classification model, etc).
    Defaults to "../data/", relative to the "src" directory.
 PAPERLESS_TRASH_DIR=<path>
    Instead of removing deleted documents, they are moved to this directory.
    This must be writeable by the user running paperless. When running inside
    docker, ensure that this path is within a permanent volume (such as
    "../media/trash") so it won't get lost on upgrades.
    Defaults to empty (i.e. really delete documents).
 PAPERLESS_MEDIA_ROOT=<path>
    This is where your documents and thumbnails are stored.
    You can set this and PAPERLESS_DATA_DIR to the same folder to have paperless
    store all its data within the same volume.
    Defaults to "../media/", relative to the "src" directory.
 PAPERLESS_STATICDIR=<path>
    Override the default STATIC_ROOT here.  This is where all static files
    created using "collectstatic" manager command are stored.
    Unless you're doing something fancy, there is no need to override this.
    Defaults to "../static/", relative to the "src" directory.
 PAPERLESS_FILENAME_FORMAT=<format>
    Changes the filenames paperless uses to store documents in the media directory.
    See :ref:`advanced-file_name_handling` for details.
    Default is none, which disables this feature.
 PAPERLESS_FILENAME_FORMAT_REMOVE_NONE=<bool>
    Tells paperless to replace placeholders in `PAPERLESS_FILENAME_FORMAT` that would resolve
    to 'none' to be omitted from the resulting filename. This also holds true for directory
    names.
    See :ref:`advanced-file_name_handling` for details.
    Defaults to `false` which disables this feature.
 PAPERLESS_LOGGING_DIR=<path>
    This is where paperless will store log files.
    Defaults to "``PAPERLESS_DATA_DIR``/log/".
 Logging
 #######
 PAPERLESS_LOGROTATE_MAX_SIZE=<num>
    Maximum file size for log files before they are rotated, in bytes.
    Defaults to 1 MiB.
 PAPERLESS_LOGROTATE_MAX_BACKUPS=<num>
    Number of rotated log files to keep.
    Defaults to 20.
 .. _hosting-and-security:
 Hosting & Security
 ##################
 PAPERLESS_SECRET_KEY=<key>
    Paperless uses this to make session tokens. If you expose paperless on the
    internet, you need to change this, since the default secret is well known.
    Use any sequence of characters. The more, the better. You don't need to
    remember this. Just face-roll your keyboard.
    Default is listed in the file ``src/paperless/settings.py``.
 PAPERLESS_URL=<url>
    This setting can be used to set the three options below (ALLOWED_HOSTS,
    CORS_ALLOWED_HOSTS and CSRF_TRUSTED_ORIGINS). If the other options are
    set the values will be combined with this one. Do not include a trailing
    slash. E.g. https://paperless.domain.com
    Defaults to empty string, leaving the other settings unaffected.
 PAPERLESS_CSRF_TRUSTED_ORIGINS=<comma-separated-list>
    A list of trusted origins for unsafe requests (e.g. POST). As of Django 4.0
    this is required to access the Django admin via the web.
    See https://docs.djangoproject.com/en/4.0/ref/settings/#csrf-trusted-origins
    Can also be set using PAPERLESS_URL (see above).
    Defaults to empty string, which does not add any origins to the trusted list.
 PAPERLESS_ALLOWED_HOSTS=<comma-separated-list>
    If you're planning on putting Paperless on the open internet, then you
    really should set this value to the domain name you're using.  Failing to do
    so leaves you open to HTTP host header attacks:
    https://docs.djangoproject.com/en/3.1/topics/security/#host-header-validation
    Just remember that this is a comma-separated list, so "example.com" is fine,
    as is "example.com,www.example.com", but NOT " example.com" or "example.com,"
    Can also be set using PAPERLESS_URL (see above).
    If manually set, please remember to include "localhost". Otherwise docker
    healthcheck will fail.
    Defaults to "*", which is all hosts.
 PAPERLESS_CORS_ALLOWED_HOSTS=<comma-separated-list>
    You need to add your servers to the list of allowed hosts that can do CORS
    calls. Set this to your public domain name.
    Can also be set using PAPERLESS_URL (see above).
    Defaults to "http://localhost:8000".
 PAPERLESS_FORCE_SCRIPT_NAME=<path>
    To host paperless under a subpath url like example.com/paperless you set
    this value to /paperless. No trailing slash!
    Defaults to none, which hosts paperless at "/".
 PAPERLESS_STATIC_URL=<path>
    Override the STATIC_URL here.  Unless you're hosting Paperless off a
    subdomain like /paperless/, you probably don't need to change this.
    If you do change it, be sure to include the trailing slash.
    Defaults to "/static/".
    .. note::
        When hosting paperless behind a reverse proxy like Traefik or Nginx at a subpath e.g.
        example.com/paperlessngx you will also need to set ``PAPERLESS_FORCE_SCRIPT_NAME``
        (see above).
 PAPERLESS_AUTO_LOGIN_USERNAME=<username>
    Specify a username here so that paperless will automatically perform login
    with the selected user.
    .. danger::
        Do not use this when exposing paperless on the internet. There are no
        checks in place that would prevent you from doing this.
    Defaults to none, which disables this feature.
 PAPERLESS_ADMIN_USER=<username>
    If this environment variable is specified, Paperless automatically creates
    a superuser with the provided username at start. This is useful in cases
    where you can not run the `createsuperuser` command separately, such as Kubernetes
    or AWS ECS.
    Requires `PAPERLESS_ADMIN_PASSWORD` to be set.
    .. note::
        This will not change an existing [super]user's password, nor will
        it recreate a user that already exists. You can leave this throughout
        the lifecycle of the containers.
 PAPERLESS_ADMIN_MAIL=<email>
    (Optional) Specify superuser email address. Only used when
    `PAPERLESS_ADMIN_USER` is set.
    Defaults to ``root@localhost``.
 PAPERLESS_ADMIN_PASSWORD=<password>
    Only used when `PAPERLESS_ADMIN_USER` is set.
    This will be the password of the automatically created superuser.
 PAPERLESS_COOKIE_PREFIX=<str>
    Specify a prefix that is added to the cookies used by paperless to identify
    the currently logged in user. This is useful for when you're running two
    instances of paperless on the same host.
    After changing this, you will have to login again.
    Defaults to ``""``, which does not alter the cookie names.
 PAPERLESS_ENABLE_HTTP_REMOTE_USER=<bool>
    Allows authentication via HTTP_REMOTE_USER which is used by some SSO
    applications.
    .. warning::
        This will allow authentication by simply adding a ``Remote-User: <username>`` header
        to a request. Use with care! You especially *must* ensure that any such header is not
        passed from your proxy server to paperless.
        If you're exposing paperless to the internet directly, do not use this.
        Also see the warning `in the official documentation <https://docs.djangoproject.com/en/3.1/howto/auth-remote-user/#configuration>`.
    Defaults to `false` which disables this feature.
 PAPERLESS_HTTP_REMOTE_USER_HEADER_NAME=<str>
    If `PAPERLESS_ENABLE_HTTP_REMOTE_USER` is enabled, this property allows to
    customize the name of the HTTP header from which the authenticated username
    is extracted. Values are in terms of
    [HttpRequest.META](https://docs.djangoproject.com/en/3.1/ref/request-response/#django.http.HttpRequest.META).
    Thus, the configured value must start with `HTTP_` followed by the
    normalized actual header name.
    Defaults to `HTTP_REMOTE_USER`.
 PAPERLESS_LOGOUT_REDIRECT_URL=<str>
    URL to redirect the user to after a logout. This can be used together with
    `PAPERLESS_ENABLE_HTTP_REMOTE_USER` to redirect the user back to the SSO
    application's logout page.
    Defaults to None, which disables this feature.
 .. _configuration-ocr:
 OCR settings
 ############
 Paperless uses `OCRmyPDF <https://ocrmypdf.readthedocs.io/en/latest/>`_ for
 performing OCR on documents and images. Paperless uses sensible defaults for
 most settings, but all of them can be configured to your needs.
 PAPERLESS_OCR_LANGUAGE=<lang>
    Customize the language that paperless will attempt to use when
    parsing documents.
    It should be a 3-letter language code consistent with ISO
    639: https://www.loc.gov/standards/iso639-2/php/code_list.php
    Set this to the language most of your documents are written in.
    This can be a combination of multiple languages such as ``deu+eng``,
    in which case tesseract will use whatever language matches best.
    Keep in mind that tesseract uses much more cpu time with multiple
    languages enabled.
    Defaults to "eng".
 		Note: If your language contains a '-' such as chi-sim, you must use chi_sim
 PAPERLESS_OCR_MODE=<mode>
    Tell paperless when and how to perform ocr on your documents. Four modes
    are available:
    *   ``skip``: Paperless skips all pages and will perform ocr only on pages
        where no text is present. This is the safest option.
    *   ``skip_noarchive``: In addition to skip, paperless won't create an
        archived version of your documents when it finds any text in them.
        This is useful if you don't want to have two almost-identical versions
        of your digital documents in the media folder. This is the fastest option.
    *   ``redo``: Paperless will OCR all pages of your documents and attempt to
        replace any existing text layers with new text. This will be useful for
        documents from scanners that already performed OCR with insufficient
        results. It will also perform OCR on purely digital documents.
        This option may fail on some documents that have features that cannot
        be removed, such as forms. In this case, the text from the document is
        used instead.
    *   ``force``: Paperless rasterizes your documents, converting any text
        into images and puts the OCRed text on top. This works for all documents,
        however, the resulting document may be significantly larger and text
        won't appear as sharp when zoomed in.
    The default is ``skip``, which only performs OCR when necessary and always
    creates archived documents.
    Read more about this in the `OCRmyPDF documentation <https://ocrmypdf.readthedocs.io/en/latest/advanced.html#when-ocr-is-skipped>`_.
 PAPERLESS_OCR_CLEAN=<mode>
    Tells paperless to use ``unpaper`` to clean any input document before
    sending it to tesseract. This uses more resources, but generally results
    in better OCR results. The following modes are available:
    *   ``clean``: Apply unpaper.
    *   ``clean-final``: Apply unpaper, and use the cleaned images to build the
        output file instead of the original images.
    *   ``none``: Do not apply unpaper.
    Defaults to ``clean``.
    .. note::
        ``clean-final`` is incompatible with ocr mode ``redo``. When both
        ``clean-final`` and the ocr mode ``redo`` is configured, ``clean``
        is used instead.
 PAPERLESS_OCR_DESKEW=<bool>
    Tells paperless to correct skewing (slight rotation of input images mainly
    due to improper scanning)
    Defaults to ``true``, which enables this feature.
    .. note::
        Deskewing is incompatible with ocr mode ``redo``. Deskewing will get
        disabled automatically if ``redo`` is used as the ocr mode.
 PAPERLESS_OCR_ROTATE_PAGES=<bool>
    Tells paperless to correct page rotation (90°, 180° and 270° rotation).
    If you notice that paperless is not rotating incorrectly rotated
    pages (or vice versa), try adjusting the threshold up or down (see below).
    Defaults to ``true``, which enables this feature.
 PAPERLESS_OCR_ROTATE_PAGES_THRESHOLD=<num>
    Adjust the threshold for automatic page rotation by ``PAPERLESS_OCR_ROTATE_PAGES``.
    This is an arbitrary value reported by tesseract. "15" is a very conservative value,
    whereas "2" is a very aggressive option and will often result in correctly rotated pages
    being rotated as well.
    Defaults to "12".
 PAPERLESS_OCR_OUTPUT_TYPE=<type>
    Specify the the type of PDF documents that paperless should produce.
    *   ``pdf``: Modify the PDF document as little as possible.
    *   ``pdfa``: Convert PDF documents into PDF/A-2b documents, which is a
        subset of the entire PDF specification and meant for storing
        documents long term.
    *   ``pdfa-1``, ``pdfa-2``, ``pdfa-3`` to specify the exact version of
        PDF/A you wish to use.
    If not specified, ``pdfa`` is used. Remember that paperless also keeps
    the original input file as well as the archived version.
 PAPERLESS_OCR_PAGES=<num>
    Tells paperless to use only the specified amount of pages for OCR. Documents
    with less than the specified amount of pages get OCR'ed completely.
    Specifying 1 here will only use the first page.
    When combined with ``PAPERLESS_OCR_MODE=redo`` or ``PAPERLESS_OCR_MODE=force``,
    paperless will not modify any text it finds on excluded pages and copy it
    verbatim.
    Defaults to 0, which disables this feature and always uses all pages.
 PAPERLESS_OCR_IMAGE_DPI=<num>
    Paperless will OCR any images you put into the system and convert them
    into PDF documents. This is useful if your scanner produces images.
    In order to do so, paperless needs to know the DPI of the image.
    Most images from scanners will have this information embedded and
    paperless will detect and use that information. In case this fails, it
    uses this value as a fallback.
    Set this to the DPI your scanner produces images at.
    Default is none, which will automatically calculate image DPI so that
    the produced PDF documents are A4 sized.
 PAPERLESS_OCR_MAX_IMAGE_PIXELS=<num>
    Paperless will raise a warning when OCRing images which are over this limit and
    will not OCR images which are more than twice this limit.  Note this does not
    prevent the document from being consumed, but could result in missing text content.
    If unset, will default to the value determined by
    `Pillow <https://pillow.readthedocs.io/en/stable/reference/Image.html#PIL.Image.MAX_IMAGE_PIXELS>`_.
    .. note::
        Increasing this limit could cause Paperless to consume additional resources
        when consuming a file.  Be sure you have sufficient system resources.
    .. caution::
        The limit is intended to prevent malicious files from consuming system resources
        and causing crashes and other errors.  Only increase this value if you are certain
        your documents are not malicious and you need the text which was not OCRed
 PAPERLESS_OCR_USER_ARGS=<json>
    OCRmyPDF offers many more options. Use this parameter to specify any
    additional arguments you wish to pass to OCRmyPDF. Since Paperless uses
    the API of OCRmyPDF, you have to specify these in a format that can be
    passed to the API. See `the API reference of OCRmyPDF <https://ocrmypdf.readthedocs.io/en/latest/api.html#reference>`_
    for valid parameters. All command line options are supported, but they
    use underscores instead of dashes.
    .. caution::
        Paperless has been tested to work with the OCR options provided
        above. There are many options that are incompatible with each other,
        so specifying invalid options may prevent paperless from consuming
        any documents.
    Specify arguments as a JSON dictionary. Keep note of lower case booleans
    and double quoted parameter names and strings. Examples:
    .. code:: json
        {"deskew": true, "optimize": 3, "unpaper_args": "--pre-rotate 90"}
 .. _configuration-tika:
 Tika settings
 #############
 Paperless can make use of `Tika <https://tika.apache.org/>`_ and
 `Gotenberg <https://gotenberg.dev/>`_ for parsing and
 converting "Office" documents (such as ".doc", ".xlsx" and ".odt"). If you
 wish to use this, you must provide a Tika server and a Gotenberg server,
 configure their endpoints, and enable the feature.
 PAPERLESS_TIKA_ENABLED=<bool>
    Enable (or disable) the Tika parser.
    Defaults to false.
 PAPERLESS_TIKA_ENDPOINT=<url>
    Set the endpoint URL were Paperless can reach your Tika server.
    Defaults to "http://localhost:9998".
 PAPERLESS_TIKA_GOTENBERG_ENDPOINT=<url>
    Set the endpoint URL were Paperless can reach your Gotenberg server.
    Defaults to "http://localhost:3000".
 If you run paperless on docker, you can add those services to the docker-compose
 file (see the provided ``docker-compose.sqlite-tika.yml`` file for reference). The changes
 requires are as follows:
 .. code:: yaml
    services:
        # ...
        webserver:
            # ...
            environment:
                # ...
                PAPERLESS_TIKA_ENABLED: 1
                PAPERLESS_TIKA_GOTENBERG_ENDPOINT: http://gotenberg:3000
                PAPERLESS_TIKA_ENDPOINT: http://tika:9998
        # ...
        gotenberg:
            image: gotenberg/gotenberg:7.6
            restart: unless-stopped
            command:
                - "gotenberg"
                - "--chromium-disable-routes=true"
        tika:
            image: ghcr.io/paperless-ngx/tika:latest
            restart: unless-stopped
 Add the configuration variables to the environment of the webserver (alternatively
 put the configuration in the ``docker-compose.env`` file) and add the additional
 services below the webserver service. Watch out for indentation.
 Make sure to use the correct format `PAPERLESS_TIKA_ENABLED = 1` so python_dotenv can parse the statement correctly.
 Software tweaks
 ###############
 PAPERLESS_TASK_WORKERS=<num>
    Paperless does multiple things in the background: Maintain the search index,
    maintain the automatic matching algorithm, check emails, consume documents,
    etc. This variable specifies how many things it will do in parallel.
    Defaults to 1
 PAPERLESS_THREADS_PER_WORKER=<num>
    Furthermore, paperless uses multiple threads when consuming documents to
    speed up OCR. This variable specifies how many pages paperless will process
    in parallel on a single document.
    .. caution::
        Ensure that the product
            PAPERLESS_TASK_WORKERS * PAPERLESS_THREADS_PER_WORKER
        does not exceed your CPU core count or else paperless will be extremely slow.
        If you want paperless to process many documents in parallel, choose a high
        worker count. If you want paperless to process very large documents faster,
        use a higher thread per worker count.
    The default is a balance between the two, according to your CPU core count,
    with a slight favor towards threads per worker:
    +----------------+---------+---------+
    | CPU core count | Workers | Threads |
    +----------------+---------+---------+
    |              1 |       1 |       1 |
    +----------------+---------+---------+
    |              2 |       2 |       1 |
    +----------------+---------+---------+
    |              4 |       2 |       2 |
    +----------------+---------+---------+
    |              6 |       2 |       3 |
    +----------------+---------+---------+
    |              8 |       2 |       4 |
    +----------------+---------+---------+
    |             12 |       3 |       4 |
    +----------------+---------+---------+
    |             16 |       4 |       4 |
    +----------------+---------+---------+
    If you only specify PAPERLESS_TASK_WORKERS, paperless will adjust
    PAPERLESS_THREADS_PER_WORKER automatically.
 PAPERLESS_WORKER_TIMEOUT=<num>
    Machines with few cores or weak ones might not be able to finish OCR on
    large documents within the default 1800 seconds. So extending this timeout
    may prove to be useful on weak hardware setups.
 PAPERLESS_WORKER_RETRY=<num>
    If PAPERLESS_WORKER_TIMEOUT has been configured, the retry time for a task can
    also be configured.  By default, this value will be set to 10s more than the
    worker timeout.  This value should never be set less than the worker timeout.
 PAPERLESS_TIME_ZONE=<timezone>
    Set the time zone here.
    See https://docs.djangoproject.com/en/3.1/ref/settings/#std:setting-TIME_ZONE
    for details on how to set it.
    Defaults to UTC.
 .. _configuration-polling:
 PAPERLESS_CONSUMER_POLLING=<num>
    If paperless won't find documents added to your consume folder, it might
    not be able to automatically detect filesystem changes. In that case,
    specify a polling interval in seconds here, which will then cause paperless
    to periodically check your consumption directory for changes. This will also
    disable listening for file system changes with ``inotify``.
    Defaults to 0, which disables polling and uses filesystem notifications.
 PAPERLESS_CONSUMER_POLLING_RETRY_COUNT=<num>
    If consumer polling is enabled, sets the number of times paperless will check for a
    file to remain unmodified.
    Defaults to 5.
 PAPERLESS_CONSUMER_POLLING_DELAY=<num>
    If consumer polling is enabled, sets the delay in seconds between each check (above) paperless
    will do while waiting for a file to remain unmodified.
    Defaults to 5.
 .. _configuration-inotify:
 PAPERLESS_CONSUMER_INOTIFY_DELAY=<num>
    Sets the time in seconds the consumer will wait for additional events
    from inotify before the consumer will consider a file ready and begin consumption.
    Certain scanners or network setups may generate multiple events for a single file,
    leading to multiple consumers working on the same file.  Configure this to
    prevent that.
    Defaults to 0.5 seconds.
 PAPERLESS_CONSUMER_DELETE_DUPLICATES=<bool>
    When the consumer detects a duplicate document, it will not touch the
    original document. This default behavior can be changed here.
    Defaults to false.
 PAPERLESS_CONSUMER_RECURSIVE=<bool>
    Enable recursive watching of the consumption directory. Paperless will
    then pickup files from files in subdirectories within your consumption
    directory as well.
    Defaults to false.
 PAPERLESS_CONSUMER_SUBDIRS_AS_TAGS=<bool>
    Set the names of subdirectories as tags for consumed files.
    E.g. <CONSUMPTION_DIR>/foo/bar/file.pdf will add the tags "foo" and "bar" to
    the consumed file. Paperless will create any tags that don't exist yet.
    This is useful for sorting documents with certain tags such as ``car`` or
    ``todo`` prior to consumption. These folders won't be deleted.
    PAPERLESS_CONSUMER_RECURSIVE must be enabled for this to work.
    Defaults to false.
 PAPERLESS_CONSUMER_ENABLE_BARCODES=<bool>
    Enables the scanning and page separation based on detected barcodes.
    This allows for scanning and adding multiple documents per uploaded
    file, which are separated by one or multiple barcode pages.
    For ease of use, it is suggested to use a standardized separation page,
    e.g. `here <https://www.alliancegroup.co.uk/patch-codes.htm>`_.
    If no barcodes are detected in the uploaded file, no page separation
    will happen.
    The original document will be removed and the separated pages will be
    saved as pdf.
    Defaults to false.
 PAPERLESS_CONSUMER_BARCODE_TIFF_SUPPORT=<bool>
    Whether TIFF image files should be scanned for barcodes.
    This will automatically convert any TIFF image(s) to pdfs for later
    processing.
    This only has an effect, if PAPERLESS_CONSUMER_ENABLE_BARCODES has been
    enabled.
    Defaults to false.
 PAPERLESS_CONSUMER_BARCODE_STRING=PATCHT
  Defines the string to be detected as a separator barcode.
  If paperless is used with the PATCH-T separator pages, users
  shouldn't change this.
  Defaults to "PATCHT"
 PAPERLESS_CONVERT_MEMORY_LIMIT=<num>
    On smaller systems, or even in the case of Very Large Documents, the consumer
    may explode, complaining about how it's "unable to extend pixel cache".  In
    such cases, try setting this to a reasonably low value, like 32.  The
    default is to use whatever is necessary to do everything without writing to
    disk, and units are in megabytes.
    For more information on how to use this value, you should search
    the web for "MAGICK_MEMORY_LIMIT".
    Defaults to 0, which disables the limit.
 PAPERLESS_CONVERT_TMPDIR=<path>
    Similar to the memory limit, if you've got a small system and your OS mounts
    /tmp as tmpfs, you should set this to a path that's on a physical disk, like
    /home/your_user/tmp or something.  ImageMagick will use this as scratch space
    when crunching through very large documents.
    For more information on how to use this value, you should search
    the web for "MAGICK_TMPDIR".
    Default is none, which disables the temporary directory.
 PAPERLESS_POST_CONSUME_SCRIPT=<filename>
    After a document is consumed, Paperless can trigger an arbitrary script if
    you like.  This script will be passed a number of arguments for you to work
    with. For more information, take a look at :ref:`advanced-post_consume_script`.
    The default is blank, which means nothing will be executed.
 PAPERLESS_FILENAME_DATE_ORDER=<format>
    Paperless will check the document text for document date information.
    Use this setting to enable checking the document filename for date
    information. The date order can be set to any option as specified in
    https://dateparser.readthedocs.io/en/latest/settings.html#date-order.
    The filename will be checked first, and if nothing is found, the document
    text will be checked as normal.
    A date in a filename must have some separators (`.`, `-`, `/`, etc)
    for it to be parsed.
    Defaults to none, which disables this feature.
 PAPERLESS_NUMBER_OF_SUGGESTED_DATES=<num>
    Paperless searches an entire document for dates. The first date found will
    be used as the initial value for the created date. When this variable is
    greater than 0 (or left to it's default value), paperless will also suggest
    other dates found in the document, up to a maximum of this setting. Note that
    duplicates will be removed, which can result in fewer dates displayed in the
    frontend than this setting value.
    The task to find all dates can be time-consuming and increases with a higher
    (maximum) number of suggested dates and slower hardware.
    Defaults to 3. Set to 0 to disable this feature.
 PAPERLESS_THUMBNAIL_FONT_NAME=<filename>
    Paperless creates thumbnails for plain text files by rendering the content
    of the file on an image and uses a predefined font for that. This
    font can be changed here.
    Note that this won't have any effect on already generated thumbnails.
    Defaults to ``/usr/share/fonts/liberation/LiberationSerif-Regular.ttf``.
 PAPERLESS_IGNORE_DATES=<string>
    Paperless parses a documents creation date from filename and file content.
    You may specify a comma separated list of dates that should be ignored during
    this process. This is useful for special dates (like date of birth) that appear
    in documents regularly but are very unlikely to be the documents creation date.
    The date is parsed using the order specified in PAPERLESS_DATE_ORDER
    Defaults to an empty string to not ignore any dates.
 PAPERLESS_DATE_ORDER=<format>
    Paperless will try to determine the document creation date from its contents.
    Specify the date format Paperless should expect to see within your documents.
    This option defaults to DMY which translates to day first, month second, and year
    last order. Characters D, M, or Y can be shuffled to meet the required order.
 PAPERLESS_CONSUMER_IGNORE_PATTERNS=<json>
    By default, paperless ignores certain files and folders in the consumption
    directory, such as system files created by the Mac OS.
    This can be adjusted by configuring a custom json array with patterns to exclude.
    Defaults to ``[".DS_STORE/*", "._*", ".stfolder/*", ".stversions/*", ".localized/*", "desktop.ini"]``.
 Binaries
 ########
 There are a few external software packages that Paperless expects to find on
 your system when it starts up.  Unless you've done something creative with
 their installation, you probably won't need to edit any of these.  However,
 if you've installed these programs somewhere where simply typing the name of
 the program doesn't automatically execute it (ie. the program isn't in your
 $PATH), then you'll need to specify the literal path for that program.
 PAPERLESS_CONVERT_BINARY=<path>
    Defaults to "convert".
 PAPERLESS_GS_BINARY=<path>
    Defaults to "gs".
 .. _configuration-docker:
 Docker-specific options
 #######################
 These options don't have any effect in ``paperless.conf``. These options adjust
 the behavior of the docker container. Configure these in `docker-compose.env`.
 PAPERLESS_WEBSERVER_WORKERS=<num>
    The number of worker processes the webserver should spawn. More worker processes
    usually result in the front end to load data much quicker. However, each worker process
    also loads the entire application into memory separately, so increasing this value
    will increase RAM usage.
    Defaults to 1.
 PAPERLESS_BIND_ADDR=<ip address>
    The IP address the webserver will listen on inside the container. There are
    special setups where you may need to configure this value to restrict the
    Ip address or interface the webserver listens on.
    Defaults to [::], meaning all interfaces, including IPv6.
 PAPERLESS_PORT=<port>
    The port number the webserver will listen on inside the container. There are
    special setups where you may need this to avoid collisions with other
    services (like using podman with multiple containers in one pod).
    Don't change this when using Docker. To change the port the webserver is
    reachable outside of the container, instead refer to the "ports" key in
    ``docker-compose.yml``.
    Defaults to 8000.
 USERMAP_UID=<uid>
    The ID of the paperless user in the container. Set this to your actual user ID on the
    host system, which you can get by executing
    .. code:: shell-session
        $ id -u
    Paperless will change ownership on its folders to this user, so you need to get this right
    in order to be able to write to the consumption directory.
    Defaults to 1000.
 USERMAP_GID=<gid>
    The ID of the paperless Group in the container. Set this to your actual group ID on the
    host system, which you can get by executing
    .. code:: shell-session
        $ id -g
    Paperless will change ownership on its folders to this group, so you need to get this right
    in order to be able to write to the consumption directory.
    Defaults to 1000.
 PAPERLESS_OCR_LANGUAGES=<list>
    Additional OCR languages to install. By default, paperless comes with
    English, German, Italian, Spanish and French. If your language is not in this list, install
    additional languages with this configuration option:
    .. code:: bash
        PAPERLESS_OCR_LANGUAGES=tur ces
    To actually use these languages, also set the default OCR language of paperless:
    .. code:: bash
        PAPERLESS_OCR_LANGUAGE=tur
    Defaults to none, which does not install any additional languages.
 PAPERLESS_ENABLE_FLOWER=<defined>
    If this environment variable is defined, the Celery monitoring tool
    `Flower <https://flower.readthedocs.io/en/latest/index.html>`_ will
    be started by the container.
    You can read more about this in the :ref:`advanced setup <advanced-celery-monitoring>`
    documentation.
 .. _configuration-update-checking:
 Update Checking
 ###############
 PAPERLESS_ENABLE_UPDATE_CHECK=<bool>
    .. note::
            This setting was deprecated in favor of a frontend setting after v1.9.2. A one-time
            migration is performed for users who have this setting set. This setting is always

 Paperless-ngx Development
-#########################
+*************************
 This section describes the steps you need to take to start development on paperless-ngx.
-Check out the source from github. The repository is organized in the following way:
+.. cssclass:: redirect-notice
-*   ``main`` always represents the latest release and will only see changes
+    The Paperless-ngx documentation has permanently moved.
    when a new release is made.
 *   ``dev`` contains the code that will be in the next release.
 *   ``feature-X`` contain bigger changes that will be in some release, but not
    necessarily the next one.
-When making functional changes to paperless, *always* make your changes on the ``dev`` branch.
+    You will be redirected shortly...
 Apart from that, the folder structure is as follows:
 *   ``docs/`` - Documentation.
 *   ``src-ui/`` - Code of the front end.
 *   ``src/`` - Code of the back end.
 *   ``scripts/`` - Various scripts that help with different parts of development.
 *   ``docker/`` - Files required to build the docker image.
 Contributing to Paperless
 =========================
 Maybe you've been using Paperless for a while and want to add a feature or two,
 or maybe you've come across a bug that you have some ideas how to solve.  The
 beauty of open source software is that you can see what's wrong and help to get
 it fixed for everyone!
 Before contributing please review our `code of conduct`_ and other important
 information in the `contributing guidelines`_.
 .. _code-formatting-with-pre-commit-hooks:
 Code formatting with pre-commit Hooks
 =====================================
 To ensure a consistent style and formatting across the project source, the project
 utilizes a Git `pre-commit` hook to perform some formatting and linting before a
 commit is allowed. That way, everyone uses the same style and some common issues
 can be caught early on. See below for installation instructions.
 Once installed, hooks will run when you commit. If the formatting isn't quite right
 or a linter catches something, the commit will be rejected. You'll need to look at the
 output and fix the issue. Some hooks, such as the Python formatting tool `black`,
 will format failing files, so all you need to do is `git add` those files again and
 retry your commit.
 Initial setup and first start
 =============================
 After you forked and cloned the code from github you need to perform a first-time setup.
 To do the setup you need to perform the steps from the following chapters in a certain order:
 1.  Install prerequisites + pipenv as mentioned in :ref:`Bare metal route <setup-bare_metal>`
 2.  Copy ``paperless.conf.example`` to ``paperless.conf`` and enable debug mode.
 3.  Install the Angular CLI interface:
    .. code:: shell-session
        $ npm install -g @angular/cli
 4.  Install pre-commit
    .. code:: shell-session
        pre-commit install
 5.  Create ``consume`` and ``media`` folders in the cloned root folder.
    .. code:: shell-session
        mkdir -p consume media
 6.  You can now either ...
    *  install redis or
    *  use the included scripts/start-services.sh to use docker to fire up a redis instance (and some other services such as tika, gotenberg and a database server) or
    *  spin up a bare redis container
        .. code:: shell-session
            docker run -d -p 6379:6379 --restart unless-stopped redis:latest
 7.  Install the python dependencies by performing in the src/ directory.
    .. code:: shell-session
        pipenv install --dev
  * Make sure you're using python 3.9.x or lower. Otherwise you might get issues with building dependencies. You can use `pyenv <https://github.com/pyenv/pyenv>`_ to install a specific python version.
 8.  Generate the static UI so you can perform a login to get session that is required for frontend development (this needs to be done one time only). From src-ui directory:
    .. code:: shell-session
        npm install .
        ./node_modules/.bin/ng build --configuration production
 9.  Apply migrations and create a superuser for your dev instance:
    .. code:: shell-session
        python3 manage.py migrate
        python3 manage.py createsuperuser
 10.  Now spin up the dev backend. Depending on which part of paperless you're developing for, you need to have some or all of them running.
    .. code:: shell-session
        python3 manage.py runserver & python3 manage.py document_consumer & celery --app paperless worker
 11. Login with the superuser credentials provided in step 8 at ``http://localhost:8000`` to create a session that enables you to use the backend.
 Backend development environment is now ready, to start Frontend development go to ``/src-ui`` and run ``ng serve``. From there you can use ``http://localhost:4200`` for a preview.
 Back end development
 ====================
 The backend is a django application. PyCharm works well for development, but you can use whatever
 you want.
 Configure the IDE to use the src/ folder as the base source folder. Configure the following
 launch configurations in your IDE:
 *   python3 manage.py runserver
 *   celery --app paperless worker
 *   python3 manage.py document_consumer
 To start them all:
 .. code:: shell-session
    python3 manage.py runserver & python3 manage.py document_consumer & celery --app paperless worker
 Testing and code style:
 *   Run ``pytest`` in the src/ directory to execute all tests. This also generates a HTML coverage
    report. When runnings test, paperless.conf is loaded as well. However: the tests rely on the default
    configuration. This is not ideal. But for now, make sure no settings except for DEBUG are overridden when testing.
 *   Coding style is enforced by the Git pre-commit hooks.  These will ensure your code is formatted and do some
    linting when you do a `git commit`.
 *   You can also run ``black`` manually to format your code
    .. note::
        The line length rule E501 is generally useful for getting multiple source files
        next to each other on the screen. However, in some cases, its just not possible
        to make some lines fit, especially complicated IF cases. Append ``# NOQA: E501``
        to disable this check for certain lines.
 Front end development
 =====================
 The front end is built using Angular. In order to get started, you need ``npm``.
 Install the Angular CLI interface with
 .. code:: shell-session
    $ npm install -g @angular/cli
 and make sure that it's on your path. Next, in the src-ui/ directory, install the
 required dependencies of the project.
 .. code:: shell-session
    $ npm install
 You can launch a development server by running
 .. code:: shell-session
    $ ng serve
 This will automatically update whenever you save. However, in-place compilation might fail
 on syntax errors, in which case you need to restart it.
 By default, the development server is available on ``http://localhost:4200/`` and is configured
 to access the API at ``http://localhost:8000/api/``, which is the default of the backend.
 If you enabled DEBUG on the back end, several security overrides for allowed hosts, CORS and
 X-Frame-Options are in place so that the front end behaves exactly as in production. This also
 relies on you being logged into the back end. Without a valid session, The front end will simply
 not work.
 Testing and code style:
 *   The frontend code (.ts, .html, .scss) use ``prettier`` for code formatting via the Git
    ``pre-commit`` hooks which run automatically on commit. See
    :ref:`above <code-formatting-with-pre-commit-hooks>` for installation. You can also run this
    via cli with a command such as
    .. code:: shell-session
        $ git ls-files -- '*.ts' | xargs pre-commit run prettier --files
 *   Frontend testing uses jest and cypress. There is currently a need for significantly more
    frontend tests. Unit tests and e2e tests, respectively, can be run non-interactively with:
    .. code:: shell-session
        $ ng test
        $ npm run e2e:ci
    Cypress also includes a UI which can be run from within the ``src-ui`` directory with
    .. code:: shell-session
        $ ./node_modules/.bin/cypress open
 In order to build the front end and serve it as part of django, execute
 .. code:: shell-session
    $ ng build --prod
 This will build the front end and put it in a location from which the Django server will serve
 it as static content. This way, you can verify that authentication is working.
 Localization
 ============
 Paperless is available in many different languages. Since paperless consists both of a django
 application and an Angular front end, both these parts have to be translated separately.
 Front end localization
 ----------------------
 *   The Angular front end does localization according to the `Angular documentation <https://angular.io/guide/i18n>`_.
 *   The source language of the project is "en_US".
 *   The source strings end up in the file "src-ui/messages.xlf".
 *   The translated strings need to be placed in the "src-ui/src/locale/" folder.
 *   In order to extract added or changed strings from the source files, call ``ng xi18n --ivy``.
 Adding new languages requires adding the translated files in the "src-ui/src/locale/" folder and adjusting a couple files.
 1.  Adjust "src-ui/angular.json":
    .. code:: json
        "i18n": {
            "sourceLocale": "en-US",
            "locales": {
                "de": "src/locale/messages.de.xlf",
                "nl-NL": "src/locale/messages.nl_NL.xlf",
                "fr": "src/locale/messages.fr.xlf",
                "en-GB": "src/locale/messages.en_GB.xlf",
                "pt-BR": "src/locale/messages.pt_BR.xlf",
                "language-code": "language-file"
            }
        }
 2.  Add the language to the available options in "src-ui/src/app/services/settings.service.ts":
    .. code:: typescript
        getLanguageOptions(): LanguageOption[] {
            return [
                {code: "en-us", name: $localize`English (US)`, englishName: "English (US)", dateInputFormat: "mm/dd/yyyy"},
                {code: "en-gb", name: $localize`English (GB)`, englishName: "English (GB)", dateInputFormat: "dd/mm/yyyy"},
                {code: "de", name: $localize`German`, englishName: "German", dateInputFormat: "dd.mm.yyyy"},
                {code: "nl", name: $localize`Dutch`, englishName: "Dutch", dateInputFormat: "dd-mm-yyyy"},
                {code: "fr", name: $localize`French`, englishName: "French", dateInputFormat: "dd/mm/yyyy"},
                {code: "pt-br", name: $localize`Portuguese (Brazil)`, englishName: "Portuguese (Brazil)", dateInputFormat: "dd/mm/yyyy"}
                // Add your new language here
            ]
        }
    ``dateInputFormat`` is a special string that defines the behavior of the date input fields and absolutely needs to contain "dd", "mm" and "yyyy".
 3.  Import and register the Angular data for this locale in "src-ui/src/app/app.module.ts":
    .. code:: typescript
        import localeDe from '@angular/common/locales/de';
        registerLocaleData(localeDe)
 Back end localization
 ---------------------
 A majority of the strings that appear in the back end appear only when the admin is used. However,
 some of these are still shown on the front end (such as error messages).
 *   The django application does localization according to the `django documentation <https://docs.djangoproject.com/en/3.1/topics/i18n/translation/>`_.
 *   The source language of the project is "en_US".
 *   Localization files end up in the folder "src/locale/".
 *   In order to extract strings from the application, call ``python3 manage.py makemessages -l en_US``. This is important after making changes to translatable strings.
 *   The message files need to be compiled for them to show up in the application. Call ``python3 manage.py compilemessages`` to do this. The generated files don't get
    committed into git, since these are derived artifacts. The build pipeline takes care of executing this command.
 Adding new languages requires adding the translated files in the "src/locale/" folder and adjusting the file "src/paperless/settings.py" to include the new language:
 .. code:: python
    LANGUAGES = [
        ("en-us", _("English (US)")),
        ("en-gb", _("English (GB)")),
        ("de", _("German")),
        ("nl-nl", _("Dutch")),
        ("fr", _("French")),
        ("pt-br", _("Portuguese (Brazil)")),
        # Add language here.
    ]
 Building the documentation
 ==========================
 The documentation is built using sphinx. I've configured ReadTheDocs to automatically build
 the documentation when changes are pushed. If you want to build the documentation locally,
 this is how you do it:
 1.  Install python dependencies.
    .. code:: shell-session
        $ cd /path/to/paperless
        $ pipenv install --dev
 2.  Build the documentation
    .. code:: shell-session
        $ cd /path/to/paperless/docs
        $ pipenv run make clean html
 This will build the HTML documentation, and put the resulting files in the ``_build/html``
 directory.
 Building the Docker image
 =========================
 The docker image is primarily built by the GitHub actions workflow, but it can be
 faster when developing to build and tag an image locally.
 To provide the build arguments automatically, build the image using the helper
 script ``build-docker-image.sh``.
 Building the docker image from source:
    .. code:: shell-session
        ./build-docker-image.sh Dockerfile -t <your-tag>
 Extending Paperless
 ===================
 Paperless does not have any fancy plugin systems and will probably never have. However,
 some parts of the application have been designed to allow easy integration of additional
 features without any modification to the base code.
 Making custom parsers
 ---------------------
 Paperless uses parsers to add documents to paperless. A parser is responsible for:
 *   Retrieve the content from the original
 *   Create a thumbnail
 *   Optional: Retrieve a created date from the original
 *   Optional: Create an archived document from the original
 Custom parsers can be added to paperless to support more file types. In order to do that,
 you need to write the parser itself and announce its existence to paperless.
 The parser itself must extend ``documents.parsers.DocumentParser`` and must implement the
 methods ``parse`` and ``get_thumbnail``. You can provide your own implementation to
 ``get_date`` if you don't want to rely on paperless' default date guessing mechanisms.
 .. code:: python
    class MyCustomParser(DocumentParser):
        def parse(self, document_path, mime_type):
            # This method does not return anything. Rather, you should assign
            # whatever you got from the document to the following fields:
            # The content of the document.
            self.text = "content"
            # Optional: path to a PDF document that you created from the original.
            self.archive_path = os.path.join(self.tempdir, "archived.pdf")
            # Optional: "created" date of the document.
            self.date = get_created_from_metadata(document_path)
        def get_thumbnail(self, document_path, mime_type):
            # This should return the path to a thumbnail you created for this
            # document.
            return os.path.join(self.tempdir, "thumb.png")
 If you encounter any issues during parsing, raise a ``documents.parsers.ParseError``.
 The ``self.tempdir`` directory is a temporary directory that is guaranteed to be empty
 and removed after consumption finished. You can use that directory to store any
 intermediate files and also use it to store the thumbnail / archived document.
 After that, you need to announce your parser to paperless. You need to connect a
 handler to the ``document_consumer_declaration`` signal. Have a look in the file
 ``src/paperless_tesseract/apps.py`` on how that's done. The handler is a method
 that returns information about your parser:
 .. code:: python
    def myparser_consumer_declaration(sender, **kwargs):
        return {
            "parser": MyCustomParser,
            "weight": 0,
            "mime_types": {
                "application/pdf": ".pdf",
                "image/jpeg": ".jpg",
            }
        }
 *   ``parser`` is a reference to a class that extends ``DocumentParser``.
 *   ``weight`` is used whenever two or more parsers are able to parse a file: The parser with
    the higher weight wins. This can be used to override the parsers provided by
    paperless.
 *   ``mime_types`` is a dictionary. The keys are the mime types your parser supports and the value
    is the default file extension that paperless should use when storing files and serving them for
    download. We could guess that from the file extensions, but some mime types have many extensions
    associated with them and the python methods responsible for guessing the extension do not always
    return the same value.

 Frequently asked questions
 **************************
 **Q:** *What's the general plan for Paperless-ngx?*
-**A:** While Paperless-ngx is already considered largely "feature-complete" it is a community-driven
+.. cssclass:: redirect-notice
 project and development will be guided in this way. New features can be submitted via
 GitHub discussions and "up-voted" by the community but this is not a guarantee the feature
 will be implemented. This project will always be open to collaboration in the form of PRs,
 ideas etc.
-**Q:** *I'm using docker. Where are my documents?*
+    The Paperless-ngx documentation has permanently moved.
-**A:** Your documents are stored inside the docker volume ``paperless_media``.
+    You will be redirected shortly...
 Docker manages this volume automatically for you. It is a persistent storage
 and will persist as long as you don't explicitly delete it. The actual location
 depends on your host operating system. On Linux, chances are high that this location
 is
 .. code::
    /var/lib/docker/volumes/paperless_media/_data
 .. caution::
    Do not mess with this folder. Don't change permissions and don't move
    files around manually. This folder is meant to be entirely managed by docker
    and paperless.
 **Q:** *Let's say I want to switch tools in a year. Can I easily move to other systems?*
 **A:** Your documents are stored as plain files inside the media folder. You can always drag those files
 out of that folder to use them elsewhere. Here are a couple notes about that.
 *   Paperless-ngx never modifies your original documents. It keeps checksums of all documents and uses a
    scheduled sanity checker to check that they remain the same.
 *   By default, paperless uses the internal ID of each document as its filename. This might not be very
    convenient for export. However, you can adjust the way files are stored in paperless by
    :ref:`configuring the filename format <advanced-file_name_handling>`.
 *   :ref:`The exporter <utilities-exporter>` is another easy way to get your files out of paperless with reasonable file names.
 **Q:** *What file types does paperless-ngx support?*
 **A:** Currently, the following files are supported:
 *   PDF documents, PNG images, JPEG images, TIFF images and GIF images are processed with OCR and converted into PDF documents.
 *   Plain text documents are supported as well and are added verbatim
    to paperless.
 *   With the optional Tika integration enabled (see :ref:`Configuration <configuration-tika>`), Paperless also supports various
    Office documents (.docx, .doc, odt, .ppt, .pptx, .odp, .xls, .xlsx, .ods).
 Paperless-ngx determines the type of a file by inspecting its content. The
 file extensions do not matter.
 **Q:** *Will paperless-ngx run on Raspberry Pi?*
 **A:** The short answer is yes. I've tested it on a Raspberry Pi 3 B.
 The long answer is that certain parts of
 Paperless will run very slow, such as the OCR. On Raspberry Pi,
 try to OCR documents before feeding them into paperless so that paperless can
 reuse the text. The web interface is a lot snappier, since it runs
 in your browser and paperless has to do much less work to serve the data.
 .. note::
    You can adjust some of the settings so that paperless uses less processing
    power. See :ref:`setup-less_powerful_devices` for details.
 **Q:** *How do I install paperless-ngx on Raspberry Pi?*
 **A:** Docker images are available for arm and arm64 hardware, so just follow
 the docker-compose instructions. Apart from more required disk space compared to
 a bare metal installation, docker comes with close to zero overhead, even on
 Raspberry Pi.
 If you decide to got with the bare metal route, be aware that some of the
 python requirements do not have precompiled packages for ARM / ARM64. Installation
 of these will require additional development libraries and compilation will take
 a long time.
 **Q:** *How do I run this on Unraid?*
 **A:** Paperless-ngx is available as `community app <https://unraid.net/community/apps?q=paperless-ngx>`_
 in Unraid. `Uli Fahrer <https://github.com/Tooa>`_ created a container template for that.
 **Q:** *How do I run this on my toaster?*
 **A:** I honestly don't know! As for all other devices that might be able
 to run paperless, you're a bit on your own. If you can't run the docker image,
 the documentation has instructions for bare metal installs. I'm running
 paperless on an i3 processor from 2015 or so. This is also what I use to test
 new releases with. Apart from that, I also have a Raspberry Pi, which I
 occasionally build the image on and see if it works.
 **Q:** *How do I proxy this with NGINX?*
 **A:** See :ref:`here <setup-nginx>`.
 .. _faq-mod_wsgi:
 **Q:** *How do I get WebSocket support with Apache mod_wsgi*?
 **A:** ``mod_wsgi`` by itself does not support ASGI. Paperless will continue
 to work with WSGI, but certain features such as status notifications about
 document consumption won't be available.
 If you want to continue using ``mod_wsgi``, you will have to run an ASGI-enabled
 web server as well that processes WebSocket connections, and configure Apache to
 redirect WebSocket connections to this server. Multiple options for ASGI servers
 exist:
 * ``gunicorn`` with ``uvicorn`` as the worker implementation (the default of paperless)
 * ``daphne`` as a standalone server, which is the reference implementation for ASGI.
 * ``uvicorn`` as a standalone server

 of a search feature, indexing is tedious, it's heavy and prone to damage &
 loss.
 I wrote this to make "going paperless" easier.  I do not have to worry about
 finding stuff again. I feed documents right from the post box into the scanner
 and then shred them.  Perhaps you might find it useful too.
 Paperless-ngx
 =============
 Paperless-ngx is a document management system that transforms your physical
 documents into a searchable online archive so you can keep, well, *less paper*.
 Paperless-ngx forked from paperless-ng to continue the great work and
 distribute responsibility of supporting and advancing the project among a team
 of people.
 NG stands for both Angular (the framework used for the
 Frontend) and next-gen. Publishing this project under a different name also
 avoids confusion between paperless and paperless-ngx.
 If you want to learn about what's different in paperless-ngx from Paperless, check out these
 resources in the documentation:
 *   :ref:`Some screenshots <screenshots>` of the new UI are available.
 *   Read :ref:`this section <advanced-automatic_matching>` if you want to
    learn about how paperless automates all tagging using machine learning.
 *   Paperless now comes with a :ref:`proper email consumer <usage-email>`
    that's fully tested and production ready.
 *   Paperless creates searchable PDF/A documents from whatever you put into
    the consumption directory. This means that you can select text in
    image-only documents coming from your scanner.
 *   See :ref:`this note <utilities-encyption>` about GnuPG encryption in
    paperless-ngx.
 *   Paperless is now integrated with a
    :ref:`task processing queue <setup-task_processor>` that tells you
    at a glance when and why something is not working.
 *   The :doc:`changelog </changelog>` contains a detailed list of all changes
    in paperless-ngx.

 Overview of Paperless-ngx
 #########################
-Compared to paperless, paperless-ngx works a little different under the hood and has
+.. cssclass:: redirect-notice
 more moving parts that work together. While this increases the complexity of
 the system, it also brings many benefits.
-Paperless consists of the following components:
+    The Paperless-ngx documentation has permanently moved.
-*   **The webserver:** This is pretty much the same as in paperless. It serves
+    You will be redirected shortly...
    the administration pages, the API, and the new frontend. This is the main
    tool you'll be using to interact with paperless. You may start the webserver
    with
    .. code:: shell-session
        $ cd /path/to/paperless/src/
        $ gunicorn -c ../gunicorn.conf.py paperless.wsgi
    or by any other means such as Apache ``mod_wsgi``.
 *   **The consumer:** This is what watches your consumption folder for documents.
    However, the consumer itself does not really consume your documents.
    Now it notifies a task processor that a new file is ready for consumption.
    I suppose it should be named differently.
    This was also used to check your emails, but that's now done elsewhere as well.
    Start the consumer with the management command ``document_consumer``:
    .. code:: shell-session
        $ cd /path/to/paperless/src/
        $ python3 manage.py document_consumer
    .. _setup-task_processor:
 *   **The task processor:** Paperless relies on `Celery - Distributed Task Queue <https://docs.celeryq.dev/en/stable/index.html>`_
    for doing most of the heavy lifting. This is a task queue that accepts tasks from
    multiple sources and processes these in parallel. It also comes with a scheduler that executes
    certain commands periodically.
    This task processor is responsible for:
    *   Consuming documents. When the consumer finds new documents, it notifies the task processor to
        start a consumption task.
    *   The task processor also performs the consumption of any documents you upload through
        the web interface.
    *   Consuming emails. It periodically checks your configured accounts for new emails and
        notifies the task processor to consume the attachment of an email.
    *   Maintaining the search index and the automatic matching algorithm. These are things that paperless
        needs to do from time to time in order to operate properly.
    This allows paperless to process multiple documents from your consumption folder in parallel! On
    a modern multi core system, this makes the consumption process with full OCR blazingly fast.
    The task processor comes with a built-in admin interface that you can use to check whenever any of the
    tasks fail and inspect the errors (i.e., wrong email credentials, errors during consuming a specific
    file, etc).
 *   A `redis <https://redis.io/>`_ message broker: This is a really lightweight service that is responsible
    for getting the tasks from the webserver and the consumer to the task scheduler. These run in a different
    process (maybe even on different machines!), and therefore, this is necessary.
 *   Optional: A database server. Paperless supports PostgreSQL, MariaDB and SQLite for storing its data.
 Installation
 ############
 You can go multiple routes to setup and run Paperless:
 * :ref:`Use the easy install docker script <setup-docker_script>`
 * :ref:`Pull the image from Docker Hub <setup-docker_hub>`
 * :ref:`Build the Docker image yourself <setup-docker_build>`
 * :ref:`Install Paperless directly on your system manually (bare metal) <setup-bare_metal>`
 The Docker routes are quick & easy. These are the recommended routes. This configures all the stuff
 from the above automatically so that it just works and uses sensible defaults for all configuration options.
 Here you find a cheat-sheet for docker beginners: `CLI Basics <https://www.sehn.tech/refs/devops-with-docker/>`_
 The bare metal route is complicated to setup but makes it easier
 should you want to contribute some code back. You need to configure and
 run the above mentioned components yourself.
 .. _CLI Basics: https://www.sehn.tech/refs/devops-with-docker/
 .. _setup-docker_script:
 Install Paperless from Docker Hub using the installation script
 ===============================================================
 Paperless provides an interactive installation script. This script will ask you
 for a couple configuration options, download and create the necessary configuration files, pull the docker image, start paperless and create your user account. This script essentially
 performs all the steps described in :ref:`setup-docker_hub` automatically.
 1.  Make sure that docker and docker-compose are installed.
 2.  Download and run the installation script:
    .. code:: shell-session
        $ bash -c "$(curl -L https://raw.githubusercontent.com/paperless-ngx/paperless-ngx/main/install-paperless-ngx.sh)"
 .. _setup-docker_hub:
 Install Paperless from Docker Hub
 =================================
 1.  Login with your user and create a folder in your home-directory `mkdir -v ~/paperless-ngx` to have a place for your configuration files and consumption directory.
 2.  Go to the `/docker/compose directory on the project page <https://github.com/paperless-ngx/paperless-ngx/tree/master/docker/compose>`_
    and download one of the `docker-compose.*.yml` files, depending on which database backend you
    want to use. Rename this file to `docker-compose.yml`.
    If you want to enable optional support for Office documents, download a file with `-tika` in the file name.
    Download the ``docker-compose.env`` file and the ``.env`` file as well and store them
    in the same directory.
    .. hint::
        For new installations, it is recommended to use PostgreSQL as the database
        backend.
 3.  Install `Docker`_ and `docker-compose`_.
    .. caution::
        If you want to use the included ``docker-compose.*.yml`` file, you
        need to have at least Docker version **17.09.0** and docker-compose
        version **1.17.0**.
        To check do: `docker-compose -v` or `docker -v`
        See the `Docker installation guide`_ on how to install the current
        version of Docker for your operating system or Linux distribution of
        choice. To get the latest version of docker-compose, follow the
        `docker-compose installation guide`_ if your package repository doesn't
        include it.
        .. _Docker installation guide: https://docs.docker.com/engine/installation/
        .. _docker-compose installation guide: https://docs.docker.com/compose/install/
 4.  Modify ``docker-compose.yml`` to your preferences. You may want to change the path
    to the consumption directory. Find the line that specifies where
    to mount the consumption directory:
    .. code::
        - ./consume:/usr/src/paperless/consume
    Replace the part BEFORE the colon with a local directory of your choice:
    .. code::
        - /home/jonaswinkler/paperless-inbox:/usr/src/paperless/consume
    Don't change the part after the colon or paperless wont find your documents.
    You may also need to change the default port that the webserver will use
    from the default (8000):
     .. code::
        ports:
          - 8000:8000
    Replace the part BEFORE the colon with a port of your choice:
     .. code::
        ports:
          - 8010:8000
    Don't change the part after the colon or edit other lines that refer to
    port 8000. Modifying the part before the colon will map requests on another
    port to the webserver running on the default port.
    **Rootless**
    If you want to run Paperless as a rootless container, you will need to do the
    following in your ``docker-compose.yml``:
    - set the ``user`` running the container to map to the ``paperless`` user in the
      container.
      This value (``user_id`` below), should be the same id that ``USERMAP_UID`` and
      ``USERMAP_GID`` are set to in the next step.
      See ``USERMAP_UID`` and ``USERMAP_GID`` :ref:`here <configuration-docker>`.
    Your entry for Paperless should contain something like:
     .. code::
        webserver:
          image: ghcr.io/paperless-ngx/paperless-ngx:latest
          user: <user_id>
 5.  Modify ``docker-compose.env``, following the comments in the file. The
    most important change is to set ``USERMAP_UID`` and ``USERMAP_GID``
    to the uid and gid of your user on the host system. Use ``id -u`` and
    ``id -g`` to get these.
    This ensures that
    both the docker container and you on the host machine have write access
    to the consumption directory. If your UID and GID on the host system is
    1000 (the default for the first normal user on most systems), it will
    work out of the box without any modifications. `id "username"` to check.
    .. note::
        You can copy any setting from the file ``paperless.conf.example`` and paste it here.
        Have a look at :ref:`configuration` to see what's available.
    .. note::
        You can utilize Docker secrets for some configuration settings by
        appending `_FILE` to some configuration values.  This is supported currently
        only by:
          * PAPERLESS_DBUSER
          * PAPERLESS_DBPASS
          * PAPERLESS_SECRET_KEY
          * PAPERLESS_AUTO_LOGIN_USERNAME
          * PAPERLESS_ADMIN_USER
          * PAPERLESS_ADMIN_MAIL
          * PAPERLESS_ADMIN_PASSWORD
    .. caution::
        Some file systems such as NFS network shares don't support file system
        notifications with ``inotify``. When storing the consumption directory
        on such a file system, paperless will not pick up new files
        with the default configuration. You will need to use ``PAPERLESS_CONSUMER_POLLING``,
        which will disable inotify. See :ref:`here <configuration-polling>`.
 6.  Run ``docker-compose pull``, followed by ``docker-compose up -d``.
    This will pull the image, create and start the necessary containers.
 7.  To be able to login, you will need a super user. To create it, execute the
    following command:
    .. code-block:: shell-session
        $ docker-compose run --rm webserver createsuperuser
    This will prompt you to set a username, an optional e-mail address and
    finally a password (at least 8 characters).
 8.  The default ``docker-compose.yml`` exports the webserver on your local port
    8000. If you did not change this, you should now be able to visit your
    Paperless instance at ``http://127.0.0.1:8000`` or your servers IP-Address:8000.
    Use the login credentials you have created with the previous step.
 .. _Docker: https://www.docker.com/
 .. _docker-compose: https://docs.docker.com/compose/install/
 .. _setup-docker_build:
 Build the Docker image yourself
 ===============================
 1.  Clone the entire repository of paperless:
    .. code:: shell-session
        git clone https://github.com/paperless-ngx/paperless-ngx
    The master branch always reflects the latest stable version.
 2.  Copy one of the ``docker/compose/docker-compose.*.yml`` to ``docker-compose.yml`` in the root folder,
    depending on which database backend you want to use. Copy
    ``docker-compose.env`` into the project root as well.
 3.  In the ``docker-compose.yml`` file, find the line that instructs docker-compose to pull the paperless image from Docker Hub:
    .. code:: yaml
        webserver:
            image: ghcr.io/paperless-ngx/paperless-ngx:latest
    and replace it with a line that instructs docker-compose to build the image from the current working directory instead:
    .. code:: yaml
        webserver:
            build:
              context: .
              args:
                QPDF_VERSION: x.y.x
                PIKEPDF_VERSION: x.y.z
                PSYCOPG2_VERSION: x.y.z
                JBIG2ENC_VERSION: 0.29
    .. note::
        You should match the build argument versions to the version for the release you have
        checked out.  These are pre-built images with certain, more updated software.
        If you want to build these images your self, that is possible, but beyond
        the scope of these steps.
 4.  Follow steps 3 to 8 of :ref:`setup-docker_hub`. When asked to run
    ``docker-compose pull`` to pull the image, do
    .. code:: shell-session
        $ docker-compose build
    instead to build the image.
 .. _setup-bare_metal:
 Bare Metal Route
 ================
 Paperless runs on linux only. The following procedure has been tested on a minimal
 installation of Debian/Buster, which is the current stable release at the time of
 writing. Windows is not and will never be supported.
 1.  Install dependencies. Paperless requires the following packages.
    *   ``python3`` 3.8, 3.9
    *   ``python3-pip``
    *   ``python3-dev``
    *   ``default-libmysqlclient-dev`` for MariaDB
    *   ``fonts-liberation`` for generating thumbnails for plain text files
    *   ``imagemagick`` >= 6 for PDF conversion
    *   ``gnupg`` for handling encrypted documents
    *   ``libpq-dev`` for PostgreSQL
    *   ``libmagic-dev`` for mime type detection
    *   ``mariadb-client`` for MariaDB compile time
    *   ``mime-support`` for mime type detection
    *   ``libzbar0`` for barcode detection
    *   ``poppler-utils`` for barcode detection
    Use this list for your preferred package management:
    .. code::
        python3 python3-pip python3-dev imagemagick fonts-liberation gnupg libpq-dev default-libmysqlclient-dev libmagic-dev mime-support libzbar0 poppler-utils
    These dependencies are required for OCRmyPDF, which is used for text recognition.
    *   ``unpaper``
    *   ``ghostscript``
    *   ``icc-profiles-free``
    *   ``qpdf``
    *   ``liblept5``
    *   ``libxml2``
    *   ``pngquant`` (suggested for certain PDF image optimizations)
    *   ``zlib1g``
    *   ``tesseract-ocr`` >= 4.0.0 for OCR
    *   ``tesseract-ocr`` language packs (``tesseract-ocr-eng``, ``tesseract-ocr-deu``, etc)
    Use this list for your preferred package management:
    .. code::
        unpaper ghostscript icc-profiles-free qpdf liblept5 libxml2 pngquant zlib1g tesseract-ocr
    On Raspberry Pi, these libraries are required as well:
    *   ``libatlas-base-dev``
    *   ``libxslt1-dev``
    You will also need ``build-essential``, ``python3-setuptools`` and ``python3-wheel``
    for installing some of the python dependencies.
 2.  Install ``redis`` >= 6.0 and configure it to start automatically.
 3.  Optional. Install ``postgresql`` and configure a database, user and password for paperless. If you do not wish
    to use PostgreSQL, MariaDB and SQLite are available as well.
    .. note::
        On bare-metal installations using SQLite, ensure the
        `JSON1 extension <https://code.djangoproject.com/wiki/JSON1Extension>`_ is enabled. This is
        usually the case, but not always.
 4.  Get the release archive from `<https://github.com/paperless-ngx/paperless-ngx/releases>`_.
    If you clone the git repo as it is, you also have to compile the front end by yourself.
    Extract the archive to a place from where you wish to execute it, such as ``/opt/paperless``.
 5.  Configure paperless. See :ref:`configuration` for details. Edit the included ``paperless.conf`` and adjust the
    settings to your needs. Required settings for getting paperless running are:
    *   ``PAPERLESS_REDIS`` should point to your redis server, such as redis://localhost:6379.
    *   ``PAPERLESS_DBENGINE`` optional, and should be one of `postgres, mariadb, or sqlite`
    *   ``PAPERLESS_DBHOST`` should be the hostname on which your PostgreSQL server is running. Do not configure this
        to use SQLite instead. Also configure port, database name, user and password as necessary.
    *   ``PAPERLESS_CONSUMPTION_DIR`` should point to a folder which paperless should watch for documents. You might
        want to have this somewhere else. Likewise, ``PAPERLESS_DATA_DIR`` and ``PAPERLESS_MEDIA_ROOT`` define where
        paperless stores its data. If you like, you can point both to the same directory.
    *   ``PAPERLESS_SECRET_KEY`` should be a random sequence of characters. It's used for authentication. Failure
        to do so allows third parties to forge authentication credentials.
    *   ``PAPERLESS_URL`` if you are behind a reverse proxy. This should point to your domain. Please see
        :ref:`configuration` for more information.
    Many more adjustments can be made to paperless, especially the OCR part. The following options are recommended
    for everyone:
    *   Set ``PAPERLESS_OCR_LANGUAGE`` to the language most of your documents are written in.
    *   Set ``PAPERLESS_TIME_ZONE`` to your local time zone.
 6.  Create a system user under which you wish to run paperless.
    .. code:: shell-session
        adduser paperless --system --home /opt/paperless --group
 7.  Ensure that these directories exist
    and that the paperless user has write permissions to the following directories:
    *   ``/opt/paperless/media``
    *   ``/opt/paperless/data``
    *   ``/opt/paperless/consume``
    Adjust as necessary if you configured different folders.
 8.  Install python requirements from the ``requirements.txt`` file.
    It is up to you if you wish to use a virtual environment or not. First you should update your pip, so it gets the actual packages.
    .. code:: shell-session
        sudo -Hu paperless pip3 install --upgrade pip
    .. code:: shell-session
        sudo -Hu paperless pip3 install -r requirements.txt
    This will install all python dependencies in the home directory of
    the new paperless user.
 9.  Go to ``/opt/paperless/src``, and execute the following commands:
    .. code:: bash
        # This creates the database schema.
        sudo -Hu paperless python3 manage.py migrate
        # This creates your first paperless user
        sudo -Hu paperless python3 manage.py createsuperuser
 10. Optional: Test that paperless is working by executing
      .. code:: bash
        # This collects static files from paperless and django.
        sudo -Hu paperless python3 manage.py runserver
    and pointing your browser to http://localhost:8000/.
    .. warning::
        This is a development server which should not be used in
        production. It is not audited for security and performance
        is inferior to production ready web servers.
    .. hint::
        This will not start the consumer. Paperless does this in a
        separate process.
 11. Setup systemd services to run paperless automatically. You may
    use the service definition files included in the ``scripts`` folder
    as a starting point.
    Paperless needs the ``webserver`` script to run the webserver, the
    ``consumer`` script to watch the input folder, ``taskqueue`` for the background workers
    used to handle things like document consumption and the ``scheduler`` script to run tasks such as
    email checking at certain times .
 		The ``socket`` script enables ``gunicorn`` to run on port 80 without
 		root privileges. For this you need to uncomment the ``Require=paperless-webserver.socket``
 		in the ``webserver`` script and configure ``gunicorn`` to listen on port 80 (see ``paperless/gunicorn.conf.py``).
    You may need to adjust the path to the ``gunicorn`` executable. This
    will be installed as part of the python dependencies, and is either located
    in the ``bin`` folder of your virtual environment, or in ``~/.local/bin/`` if
    no virtual environment is used.
    These services rely on redis and optionally the database server, but
    don't need to be started in any particular order. The example files
    depend on redis being started. If you use a database server, you should
    add additional dependencies.
    .. caution::
        The included scripts run a ``gunicorn`` standalone server,
        which is fine for running paperless. It does support SSL,
        however, the documentation of GUnicorn states that you should
        use a proxy server in front of gunicorn instead.
        For instructions on how to use nginx for that,
        :ref:`see the instructions below <setup-nginx>`.
 12. Optional: Install a samba server and make the consumption folder
    available as a network share.
 13. Configure ImageMagick to allow processing of PDF documents. Most distributions have
    this disabled by default, since PDF documents can contain malware. If
    you don't do this, paperless will fall back to ghostscript for certain steps
    such as thumbnail generation.
    Edit ``/etc/ImageMagick-6/policy.xml`` and adjust
    .. code::
        <policy domain="coder" rights="none" pattern="PDF" />
    to
    .. code::
        <policy domain="coder" rights="read|write" pattern="PDF" />
 14. Optional: Install the `jbig2enc <https://ocrmypdf.readthedocs.io/en/latest/jbig2.html>`_
    encoder. This will reduce the size of generated PDF documents. You'll most likely need
    to compile this by yourself, because this software has been patented until around 2017 and
    binary packages are not available for most distributions.
 15. Optional: If using the NLTK machine learning processing (see ``PAPERLESS_ENABLE_NLTK`` in
    :ref:`configuration` for details), download the NLTK data for the Snowball Stemmer, Stopwords
    and Punkt tokenizer to your ``PAPERLESS_DATA_DIR/nltk``.  Refer to
    the `NLTK instructions <https://www.nltk.org/data.html>`_ for details on how to
    download the data.
 Migrating to Paperless-ngx
 ##########################
 Migration is possible both from Paperless-ng or directly from the 'original' Paperless.
 Migrating from Paperless-ng
 ===========================
 Paperless-ngx is meant to be a drop-in replacement for Paperless-ng and thus upgrading should be
 trivial for most users, especially when using docker. However, as with any major change, it is
 recommended to take a full backup first. Once you are ready, simply change the docker image to
 point to the new source. E.g. if using Docker Compose, edit ``docker-compose.yml`` and change:
 .. code::
  image: jonaswinkler/paperless-ng:latest
 to
 .. code::
  image: ghcr.io/paperless-ngx/paperless-ngx:latest
 and then run ``docker-compose up -d`` which will pull the new image recreate the container.
 That's it!
 Users who installed with the bare-metal route should also update their Git clone to point to
 ``https://github.com/paperless-ngx/paperless-ngx``, e.g. using the command
 ``git remote set-url origin https://github.com/paperless-ngx/paperless-ngx`` and then pull the
 lastest version.
 Migrating from Paperless
 ========================
 At its core, paperless-ngx is still paperless and fully compatible. However, some
 things have changed under the hood, so you need to adapt your setup depending on
 how you installed paperless.
 This setup describes how to update an existing paperless Docker installation.
 The important things to keep in mind are as follows:
 * Read the :doc:`changelog </changelog>` and take note of breaking changes.
 * You should decide if you want to stick with SQLite or want to migrate your database
  to PostgreSQL. See :ref:`setup-sqlite_to_psql` for details on how to move your data from
  SQLite to PostgreSQL. Both work fine with paperless. However, if you already have a
  database server running for other services, you might as well use it for paperless as well.
 * The task scheduler of paperless, which is used to execute periodic tasks
  such as email checking and maintenance, requires a `redis`_ message broker
  instance. The docker-compose route takes care of that.
 * The layout of the folder structure for your documents and data remains the
  same, so you can just plug your old docker volumes into paperless-ngx and
  expect it to find everything where it should be.
 Migration to paperless-ngx is then performed in a few simple steps:
 1.  Stop paperless.
    .. code:: bash
        $ cd /path/to/current/paperless
        $ docker-compose down
 2.  Do a backup for two purposes: If something goes wrong, you still have your
    data. Second, if you don't like paperless-ngx, you can switch back to
    paperless.
 3.  Download the latest release of paperless-ngx. You can either go with the
    docker-compose files from `here <https://github.com/paperless-ngx/paperless-ngx/tree/master/docker/compose>`__
    or clone the repository to build the image yourself (see :ref:`above <setup-docker_build>`).
    You can either replace your current paperless folder or put paperless-ngx
    in a different location.
    .. caution::
        Paperless-ngx includes a ``.env`` file. This will set the
        project name for docker compose to ``paperless``, which will also define the name
        of the volumes by paperless-ngx. However, if you experience that paperless-ngx
        is not using your old paperless volumes, verify the names of your volumes with
        .. code:: shell-session
            $ docker volume ls | grep _data
        and adjust the project name in the ``.env`` file so that it matches the name
        of the volumes before the ``_data`` part.
 4.  Download the ``docker-compose.sqlite.yml`` file to ``docker-compose.yml``.
    If you want to switch to PostgreSQL, do that after you migrated your existing
    SQLite database.
 5.  Adjust ``docker-compose.yml`` and ``docker-compose.env`` to your needs.
    See :ref:`setup-docker_hub` for details on which edits are advised.
 6.  :ref:`Update paperless. <administration-updating>`
 7.  In order to find your existing documents with the new search feature, you need
    to invoke a one-time operation that will create the search index:
    .. code:: shell-session
        $ docker-compose run --rm webserver document_index reindex
    This will migrate your database and create the search index. After that,
    paperless will take care of maintaining the index by itself.
 8.  Start paperless-ngx.
    .. code:: bash
        $ docker-compose up -d
    This will run paperless in the background and automatically start it on system boot.
 9.  Paperless installed a permanent redirect to ``admin/`` in your browser. This
    redirect is still in place and prevents access to the new UI. Clear your
    browsing cache in order to fix this.
 10.  Optionally, follow the instructions below to migrate your existing data to PostgreSQL.
 Migrating from LinuxServer.io Docker Image
 ==========================================
 As with any upgrades and large changes, it is highly recommended to create a backup before
 starting.  This assumes the image was running using Docker Compose, but the instructions
 are translatable to Docker commands as well.
 1.  Stop and remove the paperless container
 2.  If using an external database, stop the container
 3.  Update Redis configuration
    a)  If ``REDIS_URL`` is already set, change it to ``PAPERLESS_REDIS`` and continue
        to step 4.
    b)  Otherwise, in the ``docker-compose.yml`` add a new service for Redis,
        following `the example compose files <https://github.com/paperless-ngx/paperless-ngx/tree/main/docker/compose>`_
    c)  Set the environment variable ``PAPERLESS_REDIS`` so it points to the new Redis container
 4.  Update user mapping
    a)  If set, change the environment variable ``PUID`` to ``USERMAP_UID``
    b)  If set, change the environment variable ``PGID`` to ``USERMAP_GID``
 5.  Update configuration paths
    a) Set the environment variable ``PAPERLESS_DATA_DIR``
       to ``/config``
 6.  Update media paths
    a) Set the environment variable ``PAPERLESS_MEDIA_ROOT``
       to ``/data/media``
 7.  Update timezone
    a) Set the environment variable ``PAPERLESS_TIME_ZONE``
       to the same value as ``TZ``
 8.  Modify the ``image:`` to point to ``ghcr.io/paperless-ngx/paperless-ngx:latest`` or
    a specific version if preferred.
 9.  Start the containers as before, using ``docker-compose``.
 .. _setup-sqlite_to_psql:
 Moving data from SQLite to PostgreSQL or MySQL/MariaDB
 ======================================================
 Moving your data from SQLite to PostgreSQL or MySQL/MariaDB is done via executing a series of django
 management commands as below.  The commands below use PostgreSQL, but are applicable to MySQL/MariaDB
 with the
 .. caution::
    Make sure that your SQLite database is migrated to the latest version.
    Starting paperless will make sure that this is the case. If your try to
    load data from an old database schema in SQLite into a newer database
    schema in PostgreSQL, you will run into trouble.
 .. warning::
    On some database fields, PostgreSQL enforces predefined limits on maximum
    length, whereas SQLite does not. The fields in question are the title of documents
    (128 characters), names of document types, tags and correspondents (128 characters),
    and filenames (1024 characters). If you have data in these fields that surpasses these
    limits, migration to PostgreSQL is not possible and will fail with an error.
 .. warning::
    MySQL is case insensitive by default, treating values like "Name" and "NAME" as identical.
    See :ref:`advanced-mysql-caveats` for details.
 1.  Stop paperless, if it is running.
 2.  Tell paperless to use PostgreSQL:
    a)  With docker, copy the provided ``docker-compose.postgres.yml`` file to
        ``docker-compose.yml``. Remember to adjust the consumption directory,
        if necessary.
    b)  Without docker, configure the database in your ``paperless.conf`` file.
        See :ref:`configuration` for details.
 3.  Open a shell and initialize the database:
    a)  With docker, run the following command to open a shell within the paperless
        container:
        .. code:: shell-session
            $ cd /path/to/paperless
            $ docker-compose run --rm webserver /bin/bash
        This will launch the container and initialize the PostgreSQL database.
    b)  Without docker, remember to activate any virtual environment, switch to
        the ``src`` directory and create the database schema:
        .. code:: shell-session
            $ cd /path/to/paperless/src
            $ python3 manage.py migrate
        This will not copy any data yet.
 4.  Dump your data from SQLite:
    .. code:: shell-session
        $ python3 manage.py dumpdata --database=sqlite --exclude=contenttypes --exclude=auth.Permission > data.json
 5.  Load your data into PostgreSQL:
    .. code:: shell-session
        $ python3 manage.py loaddata data.json
 6.  If operating inside Docker, you may exit the shell now.
    .. code:: shell-session
        $ exit
 7.  Start paperless.
 Moving back to Paperless
 ========================
 Lets say you migrated to Paperless-ngx and used it for a while, but decided that
 you don't like it and want to move back (If you do, send me a mail about what
 part you didn't like!), you can totally do that with a few simple steps.
 Paperless-ngx modified the database schema slightly, however, these changes can
 be reverted while keeping your current data, so that your current data will
 be compatible with original Paperless.
 Execute this:
 .. code:: shell-session
    $ cd /path/to/paperless
    $ docker-compose run --rm webserver migrate documents 0023
 Or without docker:
 .. code:: shell-session
    $ cd /path/to/paperless/src
    $ python3 manage.py migrate documents 0023
 After that, you need to clear your cookies (Paperless-ngx comes with updated
 dependencies that do cookie-processing differently) and probably your cache
 as well.
 .. _setup-less_powerful_devices:
 Considerations for less powerful devices
 ########################################
 Paperless runs on Raspberry Pi. However, some things are rather slow on the Pi and
 configuring some options in paperless can help improve performance immensely:
 *   Stick with SQLite to save some resources.
 *   Consider setting ``PAPERLESS_OCR_PAGES`` to 1, so that paperless will only OCR
    the first page of your documents. In most cases, this page contains enough
    information to be able to find it.
 *   ``PAPERLESS_TASK_WORKERS`` and ``PAPERLESS_THREADS_PER_WORKER`` are configured
    to use all cores. The Raspberry Pi models 3 and up have 4 cores, meaning that
    paperless will use 2 workers and 2 threads per worker. This may result in
    sluggish response times during consumption, so you might want to lower these
    settings (example: 2 workers and 1 thread to always have some computing power
    left for other tasks).
 *   Keep ``PAPERLESS_OCR_MODE`` at its default value ``skip`` and consider OCR'ing
    your documents before feeding them into paperless. Some scanners are able to
    do this! You might want to even specify ``skip_noarchive`` to skip archive
    file generation for already ocr'ed documents entirely.
 *   If you want to perform OCR on the device, consider using ``PAPERLESS_OCR_CLEAN=none``.
    This will speed up OCR times and use less memory at the expense of slightly worse
    OCR results.
 *   If using docker, consider setting ``PAPERLESS_WEBSERVER_WORKERS`` to
    1. This will save some memory.
 *   Consider setting ``PAPERLESS_ENABLE_NLTK`` to false, to disable the more
    advanced language processing, which can take more memory and processing time.
 For details, refer to :ref:`configuration`.
 .. note::
    Updating the :ref:`automatic matching algorithm <advanced-automatic_matching>`
    takes quite a bit of time. However, the update mechanism checks if your
    data has changed before doing the heavy lifting. If you experience the
    algorithm taking too much cpu time, consider changing the schedule in the
    admin interface to daily. You can also manually invoke the task
    by changing the date and time of the next run to today/now.
    The actual matching of the algorithm is fast and works on Raspberry Pi as
    well as on any other device.
 .. _redis: https://redis.io/
 .. _setup-nginx:
 Using nginx as a reverse proxy
 ##############################
 If you want to expose paperless to the internet, you should hide it behind a
 reverse proxy with SSL enabled.
 In addition to the usual configuration for SSL,
 the following configuration is required for paperless to operate:
 .. code:: nginx
    http {
        # Adjust as required. This is the maximum size for file uploads.
        # The default value 1M might be a little too small.
        client_max_body_size 10M;
        server {
            location / {
                # Adjust host and port as required.
                proxy_pass http://localhost:8000/;
                # These configuration options are required for WebSockets to work.
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "upgrade";
                proxy_redirect off;
                proxy_set_header Host $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header X-Forwarded-Host $server_name;
            }
        }
    }
 The ``PAPERLESS_URL`` configuration variable is also required when using a reverse proxy. Please refer to the :ref:`hosting-and-security` docs.
 Also read `this <https://channels.readthedocs.io/en/stable/deploying.html#nginx-supervisor-ubuntu>`__, towards the end of the section.

 Troubleshooting
 ***************
 No files are added by the consumer
 ##################################
-Check for the following issues:
+.. cssclass:: redirect-notice
-*   Ensure that the directory you're putting your documents in is the folder
+    The Paperless-ngx documentation has permanently moved.
    paperless is watching. With docker, this setting is performed in the
    ``docker-compose.yml`` file. Without docker, look at the ``CONSUMPTION_DIR``
    setting. Don't adjust this setting if you're using docker.
 *   Ensure that redis is up and running. Paperless does its task processing
    asynchronously, and for documents to arrive at the task processor, it needs
    redis to run.
 *   Ensure that the task processor is running. Docker does this automatically.
    Manually invoke the task processor by executing
-    .. code:: shell-session
+    You will be redirected shortly...
        $ celery --app paperless worker
 *   Look at the output of paperless and inspect it for any errors.
 *   Go to the admin interface, and check if there are failed tasks. If so, the
    tasks will contain an error message.
 Consumer warns ``OCR for XX failed``
 ####################################
 If you find the OCR accuracy to be too low, and/or the document consumer warns
 that ``OCR for XX failed, but we're going to stick with what we've got since
 FORGIVING_OCR is enabled``, then you might need to install the
 `Tesseract language files <http://packages.ubuntu.com/search?keywords=tesseract-ocr>`_
 marching your document's languages.
 As an example, if you are running Paperless-ngx from any Ubuntu or Debian
 box, and your documents are written in Spanish you may need to run::
    apt-get install -y tesseract-ocr-spa
 Consumer fails to pickup any new files
 ######################################
 If you notice that the consumer will only pickup files in the consumption
 directory at startup, but won't find any other files added later, you will need to
 enable filesystem polling with the configuration option
 ``PAPERLESS_CONSUMER_POLLING``, see :ref:`here <configuration-polling>`.
 This will disable listening to filesystem changes with inotify and paperless will
 manually check the consumption directory for changes instead.
 Paperless always redirects to /admin
 ####################################
 You probably had the old paperless installed at some point. Paperless installed
 a permanent redirect to /admin in your browser, and you need to clear your
 browsing data / cache to fix that.
 Operation not permitted
 #######################
 You might see errors such as:
 .. code:: shell-session
    chown: changing ownership of '../export': Operation not permitted
 The container tries to set file ownership on the listed directories. This is
 required so that the user running paperless inside docker has write permissions
 to these folders. This happens when pointing these directories to NFS shares,
 for example.
 Ensure that ``chown`` is possible on these directories.
 Classifier error: No training data available
 ############################################
 This indicates that the Auto matching algorithm found no documents to learn from.
 This may have two reasons:
 *   You don't use the Auto matching algorithm: The error can be safely ignored in this case.
 *   You are using the Auto matching algorithm: The classifier explicitly excludes documents
    with Inbox tags. Verify that there are documents in your archive without inbox tags.
    The algorithm will only learn from documents not in your inbox.
 UserWarning in sklearn on every single document
 ###############################################
 You may encounter warnings like this:
 .. code::
    /usr/local/lib/python3.7/site-packages/sklearn/base.py:315:
    UserWarning: Trying to unpickle estimator CountVectorizer from version 0.23.2 when using version 0.24.0.
    This might lead to breaking code or invalid results. Use at your own risk.
 This happens when certain dependencies of paperless that are responsible for the auto matching algorithm are
 updated. After updating these, your current training data *might* not be compatible anymore. This can be ignored
 in most cases. This warning will disappear automatically when paperless updates the training data.
 If you want to get rid of the warning or actually experience issues with automatic matching, delete
 the file ``classification_model.pickle`` in the data directory and let paperless recreate it.
 504 Server Error: Gateway Timeout when adding Office documents
 ##############################################################
 You may experience these errors when using the optional TIKA integration:
 .. code::
    requests.exceptions.HTTPError: 504 Server Error: Gateway Timeout for url: http://gotenberg:3000/forms/libreoffice/convert
 Gotenberg is a server that converts Office documents into PDF documents and has a default timeout of 30 seconds.
 When conversion takes longer, Gotenberg raises this error.
 You can increase the timeout by configuring a command flag for Gotenberg (see also `here <https://gotenberg.dev/docs/modules/api#properties>`__).
 If using docker-compose, this is achieved by the following configuration change in the ``docker-compose.yml`` file:
 .. code:: yaml
    gotenberg:
        image: gotenberg/gotenberg:7.6
        restart: unless-stopped
        command:
            - "gotenberg"
            - "--chromium-disable-routes=true"
            - "--api-timeout=60"
 Permission denied errors in the consumption directory
 #####################################################
 You might encounter errors such as:
 .. code:: shell-session
    The following error occured while consuming document.pdf: [Errno 13] Permission denied: '/usr/src/paperless/src/../consume/document.pdf'
 This happens when paperless does not have permission to delete files inside the consumption directory.
 Ensure that ``USERMAP_UID`` and ``USERMAP_GID`` are set to the user id and group id you use on the host operating system, if these are
 different from ``1000``. See :ref:`setup-docker_hub`.
 Also ensure that you are able to read and write to the consumption directory on the host.
 OSError: [Errno 19] No such device when consuming files
 #######################################################
 If you experience errors such as:
 .. code:: shell-session
    File "/usr/local/lib/python3.7/site-packages/whoosh/codec/base.py", line 570, in open_compound_file
    return CompoundStorage(dbfile, use_mmap=storage.supports_mmap)
    File "/usr/local/lib/python3.7/site-packages/whoosh/filedb/compound.py", line 75, in __init__
    self._source = mmap.mmap(fileno, 0, access=mmap.ACCESS_READ)
    OSError: [Errno 19] No such device
    During handling of the above exception, another exception occurred:
    Traceback (most recent call last):
    File "/usr/local/lib/python3.7/site-packages/django_q/cluster.py", line 436, in worker
    res = f(*task["args"], **task["kwargs"])
    File "/usr/src/paperless/src/documents/tasks.py", line 73, in consume_file
    override_tag_ids=override_tag_ids)
    File "/usr/src/paperless/src/documents/consumer.py", line 271, in try_consume_file
    raise ConsumerError(e)
 Paperless uses a search index to provide better and faster full text searching. This search index is stored inside
 the ``data`` folder. The search index uses memory-mapped files (mmap). The above error indicates that paperless
 was unable to create and open these files.
 This happens when you're trying to store the data directory on certain file systems (mostly network shares)
 that don't support memory-mapped files.
 Web-UI stuck at "Loading..."
 ############################
 This might have multiple reasons.
 1.  If you built the docker image yourself or deployed using the bare metal route,
    make sure that there are files in ``<paperless-root>/static/frontend/<lang-code>/``.
    If there are no files, make sure that you executed ``collectstatic`` successfully, either
    manually or as part of the docker image build.
    If the front end is still missing, make sure that the front end is compiled (files present in
    ``src/documents/static/frontend``). If it is not, you need to compile the front end yourself
    or download the release archive instead of cloning the repository.
 2.  Check the output of the web server. You might see errors like this:
    .. code::
        [2021-01-25 10:08:04 +0000] [40] [ERROR] Socket error processing request.
        Traceback (most recent call last):

            sent += os.sendfile(sockno, fileno, offset + sent, count)
        OSError: [Errno 22] Invalid argument
    To fix this issue, add
    .. code::
        SENDFILE=0
    to your `docker-compose.env` file.
 Error while reading metadata
 ############################
 You might find messages like these in your log files:
 .. code::
    [WARNING] [paperless.parsing.tesseract] Error while reading metadata
 This indicates that paperless failed to read PDF metadata from one of your documents. This happens when you
 open the affected documents in paperless for editing. Paperless will continue to work, and will simply not
 show the invalid metadata.
 Consumer fails with a FileNotFoundError
 #######################################
 You might find messages like these in your log files:
 .. code::

        pdf = Pdf._open(
    FileNotFoundError: [Errno 2] No such file or directory: '/tmp/ocrmypdf.io.yhk3zbv0/origin.pdf'
 This probably indicates paperless tried to consume the same file twice.  This can happen for a number of reasons,
 depending on how documents are placed into the consume folder.  If paperless is using inotify (the default) to
 check for documents, try adjusting the :ref:`inotify configuration <configuration-inotify>`.  If polling is enabled,
 try adjusting the :ref:`polling configuration <configuration-polling>`.
 Consumer fails waiting for file to remain unmodified.

 You might find messages like these in your log files:
 .. code::
    [ERROR] [paperless.management.consumer] Creating PaperlessTask failed: db locked
 You are likely using an sqlite based installation, with an increased number of workers and are running into sqlite's concurrency limitations.
 Uploading or consuming multiple files at once results in many workers attempting to access the database simultaneously.
 Consider changing to the PostgreSQL database if you will be processing many documents at once often.  Otherwise,
 try tweaking the ``PAPERLESS_DB_TIMEOUT`` setting to allow more time for the database to unlock.  This may have
 minor performance implications.
 gunicorn fails to start with "is not a valid port number"
 #########################################################
 You are likely running using Kubernetes, which automatically creates an environment variable named `${serviceName}_PORT`.
 This is the same environment variable which is used by Paperless to optionally change the port gunicorn listens on.
 To fix this, set `PAPERLESS_PORT` again to your desired port, or the default of 8000.

 Usage Overview
 **************
 Paperless is an application that manages your personal documents. With
 the help of a document scanner (see :ref:`scanners`), paperless transforms
 your wieldy physical document binders into a searchable archive and
 provides many utilities for finding and managing your documents.
 .. cssclass:: redirect-notice

 documents:
 * The *consumer* watches a specified folder and adds all documents in that
  folder to paperless.
 * The *web server* provides a UI that you use to manage and search for your
  scanned documents.
 Each document has a couple of fields that you can assign to them:
 * A *Document* is a piece of paper that sometimes contains valuable
  information.
 * The *correspondent* of a document is the person, institution or company that
  a document either originates from, or is sent to.
 * A *tag* is a label that you can assign to documents. Think of labels as more
  powerful folders: Multiple documents can be grouped together with a single
  tag, however, a single document can also have multiple tags. This is not
  possible with folders. The reason folders are not implemented in paperless
  is simply that tags are much more versatile than folders.
 * A *document type* is used to demarcate the type of a document such as letter,
  bank statement, invoice, contract, etc. It is used to identify what a document
  is about.
 * The *date added* of a document is the date the document was scanned into
  paperless. You cannot and should not change this date.
 * The *date created* of a document is the date the document was initially issued.
  This can be the date you bought a product, the date you signed a contract, or
  the date a letter was sent to you.
 * The *archive serial number* (short: ASN) of a document is the identifier of
  the document in your physical document binders. See
  :ref:`usage-recommended_workflow` below.
 * The *content* of a document is the text that was OCR'ed from the document.
  This text is fed into the search engine and is used for matching tags,
  correspondents and document types.

 Adding documents to paperless
 #############################
 Once you've got Paperless setup, you need to start feeding documents into it.
 When adding documents to paperless, it will perform the following operations on
 your documents:
 1.  OCR the document, if it has no text. Digital documents usually have text,
    and this step will be skipped for those documents.
 2.  Paperless will create an archivable PDF/A document from your document.
    If this document is coming from your scanner, it will have embedded selectable text.
 3.  Paperless performs automatic matching of tags, correspondents and types on the
    document before storing it in the database.
 .. hint::
    This process can be configured to fit your needs. If you don't want paperless
    to create archived versions for digital documents, you can configure that by
    configuring ``PAPERLESS_OCR_MODE=skip_noarchive``. Please read the
    :ref:`relevant section in the documentation <configuration-ocr>`.
 .. note::
    No matter which options you choose, Paperless will always store the original
    document that it found in the consumption directory or in the mail and
    will never overwrite that document. Archived versions are stored alongside the
    original versions.
 The consumption directory
 =========================
 The primary method of getting documents into your database is by putting them in
 the consumption directory.  The consumer runs in an infinite loop, looking for new
 additions to this directory. When it finds them, the consumer goes about the process
 of parsing them with the OCR, indexing what it finds, and storing it in the media directory.
 Getting stuff into this directory is up to you.  If you're running Paperless
 on your local computer, you might just want to drag and drop files there, but if
 you're running this on a server and want your scanner to automatically push
 files to this directory, you'll need to setup some sort of service to accept the
 files from the scanner.  Typically, you're looking at an FTP server like
 `Proftpd`_ or a Windows folder share with `Samba`_.
 .. _Proftpd: http://www.proftpd.org/
 .. _Samba: http://www.samba.org/
 .. TODO: hyperref to configuration of the location of this magic folder.
 Web UI Upload
 =============
 The dashboard has a file drop field to upload documents to paperless. Simply drag a file
 onto this field or select a file with the file dialog. Multiple files are supported.
 You can also upload documents on any other page of the web UI by dragging-and-dropping
 files into your browser window.
 .. _usage-mobile_upload:
 Mobile upload
 =============
 The mobile app over at `<https://github.com/qcasey/paperless_share>`_ allows Android users
 to share any documents with paperless. This can be combined with any of the mobile
 scanning apps out there, such as Office Lens.
 Furthermore, there is the  `Paperless App <https://github.com/bauerj/paperless_app>`_ as well,
 which not only has document upload, but also document browsing and download features.
 .. _usage-email:
 IMAP (Email)
 ============
 You can tell paperless-ngx to consume documents from your email accounts.
 This is a very flexible and powerful feature, if you regularly received documents
 via mail that you need to archive. The mail consumer can be configured by using the
 admin interface in the following manner:
 1.  Define e-mail accounts.
 2.  Define mail rules for your account.
 These rules perform the following:
 1.  Connect to the mail server.
 2.  Fetch all matching mails (as defined by folder, maximum age and the filters)
 3.  Check if there are any consumable attachments.
 4.  If so, instruct paperless to consume the attachments and optionally
    use the metadata provided in the rule for the new document.
 5.  If documents were consumed from a mail, the rule action is performed
    on that mail.
 Paperless will completely ignore mails that do not match your filters. It will also
 only perform the action on mails that it has consumed documents from.
 The actions all ensure that the same mail is not consumed twice by different means.
 These are as follows:
 *   **Delete:** Immediately deletes mail that paperless has consumed documents from.
    Use with caution.
 *   **Mark as read:** Mark consumed mail as read. Paperless will not consume documents
    from already read mails. If you read a mail before paperless sees it, it will be
    ignored.
 *   **Flag:** Sets the 'important' flag on mails with consumed documents. Paperless
    will not consume flagged mails.
 *   **Move to folder:** Moves consumed mails out of the way so that paperless wont
    consume them again.
 *   **Add custom Tag:** Adds a custom tag to mails with consumed documents (the IMAP
    standard calls these "keywords"). Paperless will not consume mails already tagged.
    Not all mail servers support this feature!
 .. caution::
    The mail consumer will perform these actions on all mails it has consumed
    documents from. Keep in mind that the actual consumption process may fail
    for some reason, leaving you with missing documents in paperless.
 .. note::
    With the correct set of rules, you can completely automate your email documents.
    Create rules for every correspondent you receive digital documents from and
    paperless will read them automatically. The default action "mark as read" is
    pretty tame and will not cause any damage or data loss whatsoever.
    You can also setup a special folder in your mail account for paperless and use
    your favorite mail client to move to be consumed mails into that folder
    automatically or manually and tell paperless to move them to yet another folder
    after consumption. It's up to you.
 .. note::
    When defining a mail rule with a folder, you may need to try different characters to
    define how the sub-folders are separated.  Common values include ".", "/" or "|", but
    this varies by the mail server.  Check the documentation for your mail server.  In the
    event of an error fetching mail from a certain folder, check the Paperless logs.  When
    a folder is not located, Paperless will attempt to list all folders found in the account
    to the Paperless logs.
 .. note::
    Paperless will process the rules in the order defined in the admin page.
    You can define catch-all rules and have them executed last to consume
    any documents not matched by previous rules. Such a rule may assign an "Unknown
    mail document" tag to consumed documents so you can inspect them further.
 Paperless is set up to check your mails every 10 minutes. This can be configured on the
 'Scheduled tasks' page in the admin.
 REST API
 ========
 You can also submit a document using the REST API, see :ref:`api-file_uploads` for details.

 Best practices
 ##############
 Paperless offers a couple tools that help you organize your document collection. However,
 it is up to you to use them in a way that helps you organize documents and find specific
 documents when you need them. This section offers a couple ideas for managing your collection.
 Document types allow you to classify documents according to what they are. You can define
 types such as "Receipt", "Invoice", or "Contract". If you used to collect all your receipts
 in a single binder, you can recreate that system in paperless by defining a document type,
 assigning documents to that type and then filtering by that type to only see all receipts.
 Not all documents need document types. Sometimes its hard to determine what the type of a
 document is or it is hard to justify creating a document type that you only need once or twice.
 This is okay. As long as the types you define help you organize your collection in the way
 you want, paperless is doing its job.
 Tags can be used in many different ways. Think of tags are more versatile folders or binders.
 If you have a binder for documents related to university / your car or health care, you can
 create these binders in paperless by creating tags and assigning them to relevant documents.
 Just as with documents, you can filter the document list by tags and only see documents of
 a certain topic.
 With physical documents, you'll often need to decide which folder the document belongs to.
 The advantage of tags over folders and binders is that a single document can have multiple
 tags. A physical document cannot magically appear in two different folders, but with tags,
 this is entirely possible.
 .. hint::
  This can be used in many different ways. One example: Imagine you're working on a particular
  task, such as signing up for university. Usually you'll need to collect a bunch of different
  documents that are already sorted into various folders. With the tag system of paperless,
  you can create a new group of documents that are relevant to this task without destroying
  the already existing organization. When you're done with the task, you could delete the
  tag again, which would be equal to sorting documents back into the folder they belong into.
  Or keep the tag, up to you.
 All of the logic above applies to correspondents as well. Attach them to documents if you
 feel that they help you organize your collection.
 When you've started organizing your documents, create a couple saved views for document collections
 you regularly access. This is equal to having labeled physical binders on your desk, except
 that these saved views are dynamic and simply update themselves as you add documents to the system.
 Here are a couple examples of tags and types that you could use in your collection.
 * An ``inbox`` tag for newly added documents that you haven't manually edited yet.
 * A tag ``car`` for everything car related (repairs, registration, insurance, etc)
 * A tag ``todo`` for documents that you still need to do something with, such as reply, or
  perform some task online.
 * A tag ``bank account x`` for all bank statement related to that account.
 * A tag ``mail`` for anything that you added to paperless via its mail processing capabilities.
 * A tag ``missing_metadata`` when you still need to add some metadata to a document, but can't
  or don't want to do this right now.
 .. _basic-usage_searching:
 Searching
 #########
 Paperless offers an extensive searching mechanism that is designed to allow you to quickly
 find a document you're looking for (for example, that thing that just broke and you bought
 a couple months ago, that contract you signed 8 years ago).
 When you search paperless for a document, it tries to match this query against your documents.
 Paperless will look for matching documents by inspecting their content, title, correspondent,
 type and tags. Paperless returns a scored list of results, so that documents matching your query
 better will appear further up in the search results.
 By default, paperless returns only documents which contain all words typed in the search bar.
 However, paperless also offers advanced search syntax if you want to drill down the results
 further.
 Matching documents with logical expressions:
 .. code::
  shopname AND (product1 OR product2)
 Matching specific tags, correspondents or types:
 .. code::
  type:invoice tag:unpaid
  correspondent:university certificate
 Matching dates:
 .. code::
  created:[2005 to 2009]
  added:yesterday
  modified:today
 Matching inexact words:
 .. code::
  produ*name
 .. note::
  Inexact terms are hard for search indexes. These queries might take a while to execute. That's why paperless offers
  auto complete and query correction.
 All of these constructs can be combined as you see fit.
 If you want to learn more about the query language used by paperless, paperless uses Whoosh's default query language.
 Head over to `Whoosh query language <https://whoosh.readthedocs.io/en/latest/querylang.html>`_.
 For details on what date parsing utilities are available, see
 `Date parsing <https://whoosh.readthedocs.io/en/latest/dates.html#parsing-date-queries>`_.

 The recommended workflow
 ########################
 Once you have familiarized yourself with paperless and are ready to use it
 for all your documents, the recommended workflow for managing your documents
 is as follows. This workflow also takes into account that some documents
 have to be kept in physical form, but still ensures that you get all the
 advantages for these documents as well.
 The following diagram shows how easy it is to manage your documents.
 .. image:: _static/recommended_workflow.png
 Preparations in paperless
 =========================
 * Create an inbox tag that gets assigned to all new documents.
 * Create a TODO tag.
 Processing of the physical documents
 ====================================
 Keep a physical inbox. Whenever you receive a document that you need to
 archive, put it into your inbox. Regularly, do the following for all documents
 in your inbox:
 1.  For each document, decide if you need to keep the document in physical
    form. This applies to certain important documents, such as contracts and
    certificates.
 2.  If you need to keep the document, write a running number on the document
    before scanning, starting at one and counting upwards. This is the archive
    serial number, or ASN in short.
 3.  Scan the document.
 4.  If the document has an ASN assigned, store it in a *single* binder, sorted
    by ASN. Don't order this binder in any other way.
 5.  If the document has no ASN, throw it away. Yay!
 Over time, you will notice that your physical binder will fill up. If it is
 full, label the binder with the range of ASNs in this binder (i.e., "Documents
 1 to 343"), store the binder in your cellar or elsewhere, and start a new
 binder.
 The idea behind this process is that you will never have to use the physical
 binders to find a document. If you need a specific physical document, you
 may find this document by:
 1.  Searching in paperless for the document.
 2.  Identify the ASN of the document, since it appears on the scan.
 3.  Grab the relevant document binder and get the document. This is easy since
    they are sorted by ASN.
 Processing of documents in paperless
 ====================================
 Once you have scanned in a document, proceed in paperless as follows.
 1.  If the document has an ASN, assign the ASN to the document.
 2.  Assign a correspondent to the document (i.e., your employer, bank, etc)
    This isn't strictly necessary but helps in finding a document when you need
    it.
 3.  Assign a document type (i.e., invoice, bank statement, etc) to the document
    This isn't strictly necessary but helps in finding a document when you need
    it.
 4.  Assign a proper title to the document (the name of an item you bought, the
    subject of the letter, etc)
 5.  Check that the date of the document is correct. Paperless tries to read
    the date from the content of the document, but this fails sometimes if the
    OCR is bad or multiple dates appear on the document.
 6.  Remove inbox tags from the documents.
 .. hint::
    You can setup manual matching rules for your correspondents and tags and
    paperless will assign them automatically. After consuming a couple documents,
    you can even ask paperless to *learn* when to assign tags and correspondents
    by itself. For details on this feature, see :ref:`advanced-matching`.
 Task management
 ===============
 Some documents require attention and require you to act on the document. You
 may take two different approaches to handle these documents based on how
 regularly you intend to scan documents and use paperless.
 * If you scan and process your documents in paperless regularly, assign a
  TODO tag to all scanned documents that you need to process. Create a saved
  view on the dashboard that shows all documents with this tag.
 * If you do not scan documents regularly and use paperless solely for archiving,
  create a physical todo box next to your physical inbox and put documents you
  need to process in the TODO box. When you performed the task associated with
  the document, move it to the inbox.
