+=============
+
+The documentation is written in `reStructured Text`_ format, processed with
+Sphinx_, and resides in the ``docs`` directory. In order to build it, you will
+first need to install the documentation editing dependencies with::
+
+    $ pip install -r requirements/documentation.txt
+
+Then, to build an HTML version of the documentation, run the following command
+from the **docs** directory::
+
+    $ make docs-serve
+
+The generated documentation can be viewed by browsing to http://127.0.0.1:8000
+or by browsing to the ``docs/_build/html`` directory.
+
+You can also generate the documentation in formats other than HTML. Consult the
+Sphinx_ documentation for more details.
