+Coala
+=====
+
+Coala is a great tool for linting all languages. We use it here in lftools for
+linting this project and can be launched simply with python-tox as long as
+Python 3 is available on the system.
+
+.. code-block:: bash
+
+    tox -ecoala
+
+Sometimes running Coala without tox such as for running in interactive mode
+could be handy. In this case it is necessary to install Coala. The recommended
+way to setup Coala is to use a Python VirtualEnv. If possible using a script
+called virtualenvwrapper is recommended as it makes it very simple to manage
+local virtualenvs.
+
+Requirements
+------------
+
+* Python 3
+* Python VirtualEnv
+* Python VirtualEnvWrapper
+
+Install Coala
+-------------
+
+.. note::
+
+    Some distros have a package called *coala* available however do not confuse
+    this package with python-coala which is an entirely different piece of
+    software.
+
+Using virtualenv is the way this guide recommends setting up on a local system
+and will assume VirtualEnvWrapper is available. To install Coala run the
+following commands.
+
+.. code-block:: bash
+
+    mkvirtualenv --python=/usr/bin/python3 coala
+    pip install coala coala-bears
+    coala --help
+
+In future runs in a new shell you can activate the existing coala virtualenv as
+follows.
+
+.. code-block:: bash
+
+    workon coala
+    coala --help
+
+Setting up Coala a Project
+--------------------------
+
+In some cases we may want to setup coala for a new project that wants to start
+linting their project. We recommend using python-tox to manage a Coala setup
+for any projects.
+
+**Requirements**
+
+* Python 3
+* Python VirtualEnv
+* Python Tox
+
+Once requirements are met configure the project with a tox.ini and a .coafile
+file. Below are examples of .coafile and tox.ini as defined by lftools. Inside
+the tox.ini file the interesting bits are under [testenv:coala].
+
+**.coafile**
+
+.. literalinclude:: ../.coafile
+    :language: ini
+
+**tox.ini**
+
+.. literalinclude:: ../tox.ini
+    :language: ini
