+### Building Documentation
+
+We use [Sphinx](http://www.sphinx-doc.org/) to produce various documentation
+from reStructuredText (preferred) and Markdown. The Sphinx documentation has
+a useful primer for  reStructuredText
+[here](http://www.sphinx-doc.org/en/master/usage/restructuredtext/index.html).
+And the docutils website has a nice [quick
+reference](http://docutils.sourceforge.net/docs/user/rst/quickref.html) for the
+basic constructes.
