+## Sharing documents from Paperless-ngx
+
+Paperless-ngx supports sharing documents with other users by assigning them [permissions](#object-permissions)
+to the document. Document files can also be shared externally via [share links](#share-links), [email](#email-sharing)
+or using [email](#workflow-action-email) or [webhook](#workflow-action-webhook) actions in workflows.
+
+### Share Links
+
+"Share links" are shareable public links to files and can be created and managed under the 'Send' button on the document detail screen.
+
+-   Share links do not require a user to login and thus link directly to a file.
+-   Links are unique and are of the form `{paperless-url}/share/{randomly-generated-slug}`.
+-   Links can optionally have an expiration time set.
+-   After a link expires or is deleted users will be redirected to the regular paperless-ngx login.

+!!! tip
+
+    If your paperless-ngx instance is behind a reverse-proxy you may want to create an exception to bypass any authentication layers that are part of your setup in order to make links truly publicly-accessible. Of course, do so with caution.

+### Email Sharing {#email-sharing}
+
+Paperless-ngx supports directly sending documents via email. If an email server has been [configured](configuration.md#email-sending)
+the "Send" button on the document detail page will include an "Email" option. You can also share files via email automatically by using
