 Virtual Environments
 ====================
 
-.. todo:: Explain "Virtual Environments"
+A Virtual Environment, put simply, is an isolated working copy of Python which 
+allows you to work on a specific project without worry of affecting other 
+projects.
+
+For example, you can work on a project which requires Django 1.3 while also 
+maintaining a project which requires Django 1.0.
 
 virtualenv
 ----------
 
-.. todo:: Write about virtualenv
+`virtualenv <http://pypi.python.org/pypi/virtualenv>`_ is a tool to create 
+isolated Python environments.
+
+Install it via pip:
+
+.. code-block:: console
+
+  $ pip install virtualenv
+
+Basic Usage
+~~~~~~~~~~~
+
+1. Create a virtual environment:
+
+.. code-block:: console
+
+   $ virtualenv venv
+
+This creates a copy of Python in whichever directory you ran the command in, 
+placing it in a folder named ``venv``.
+
+2. To begin using the virtual environment, it needs to be activated:
+
+.. code-block:: console
+
+   $ source venv/bin/activate
+
+You can then begin installing any new modules without affecting the system 
+default Python or other virtual environments.
+
+3. If you are done working in the virtual environment for the moment, you can 
+   deactivate it:
+
+.. code-block:: console
+
+   $ deactivate
+
+This puts you back to the system's default Python interpreter with all its 
+installed libraries.
+
+To delete a virtual environment, just delete its folder.
+
+After a while, though, you might end up with a lot of virtual environments 
+littered across your system, and its possible you'll forget their names or 
+where they were placed. 
 
 virtualenvwrapper
 -----------------
 
-.. todo:: Write about virtualenvwrapper
+`virtualenvwrapper <http://www.doughellmann.com/projects/virtualenvwrapper/>`_ 
+provides a set of commands which makes working with virtual environments much 
+more pleasant. It also places all your virtual environments in one place.
 
+To install (make sure **virtualenv** is already installed):
+
+.. code-block:: console
+
+  $ pip install virtualenvwrapper
+  $ export WORKON_HOME=~/Envs
+  $ source /usr/local/bin/virtualenvwrapper.sh
+
+(`Full virtualenvwrapper install instructions <http://www.doughellmann.com/docs/virtualenvwrapper/#introduction>`_.)
+
+Basic Usage
+~~~~~~~~~~~
+
+1. Create a virtual environment:
+
+.. code-block:: console
+
+   $ mkvirtualenv venv
+
+This creates the ``venv`` folder inside ``~/Envs``. 
+
+2. Work on a virtual environment:
+
+.. code-block:: console
+
+   $ workon venv
+
+**virtualenvwrapper** provides tab-completion on environment names. It really 
+helps when you have a lot of environments and have trouble remembering their 
+names. 
+``workon`` also deactivates whatever environment you are currently in, so you 
+can quickly switch between environments.
+
+3. Deactivating is still the same:
+
+.. code-block:: console
+
+   $ deactivate
+
+4. To delete:
+
+.. code-block:: console
+
+   $ rmvirtualenv venv
+
+Other useful commands
+~~~~~~~~~~~~~~~~~~~~~
+
+``lsvirtualenv``
+  List all of the environments.
+
+``cdvirtualenv``
+  Navigate into the directory of the currently activated virtual environment, 
+  so you can browse its ``site-packages``, for example. 
+
+``cdsitepackages``
+  Like the above, but directly into ``site-packages`` directory.
+
+``lssitepackages``
+  Shows contents of ``site-packages`` directory.
