+``python3`` and ``python`` respectively.  The same goes for ``pip3`` and
+``pip``.  Using Python2 will likely break things, so make sure that you're using
+the right version.
+
+For the purposes of simplicity, ``python`` and ``pip`` is used everywhere to
+refer to their Python 3 versions.
 
 In addition to the above, there are a number of Python requirements, all of

+Python-specific Requirements: No Virtualenv
+-------------------------------------------
+
+If you don't care to use a virtual env, then installation of the Python
+dependencies is easy:
+
+.. code:: bash
+
+    $ pip install --user --requirement /path/to/paperless/requirements.txt
+
+This should download and install all of the requirements into
+``${HOME}/.local``.  Remember that your distribution may be using ``pip3`` as
+mentioned above.
+
+
+.. _requirements-virtualenv:
+
+Python-specific Requirements: Virtualenv
+----------------------------------------
+
+Using a virtualenv for this is pretty straightforward: create a virtualenv,
+enter it, and install the requirements using the ``requirements.txt`` file:
+
+.. code:: bash
+
+    $ virtualenv --python=/path/to/python3 /path/to/arbitrary/directory
+    $ . /path/to/arbitrary/directory/bin/activate
+    $ pip install  --requirement /path/to/paperless/requirements.txt
+
+Now you're ready to go.  Just remember to enter your virtualenv whenever you
+want to use *Paperless*.
