-Using a ``virtualenv``
-======================
-
-If you install your project's Python dependencies inside a `virtualenv`_,
-you'll need to add the path to this virtualenv's ``site-packages`` directory to
-your Python path as well. To do this, add an additional path to your
-``WSGIPythonPath`` directive, with multiple paths separated by a colon (``:``)
-if using a UNIX-like system, or a semicolon (``;``) if using Windows. If any
-part of a directory path contains a space character, the complete argument
-string to ``WSGIPythonPath`` must be quoted:
-
-.. code-block:: apache
-
-    WSGIPythonPath /path/to/mysite.com:/path/to/your/venv/lib/python3.X/site-packages
-
-Make sure you give the correct path to your virtualenv, and replace
-``python3.X`` with the correct Python version (e.g. ``python3.4``).
