+Documentation Guide
+===================
+
+Building the Docs
+------------------
+
+The documentation build process is stored in the Makefile. Building docs
+requires Python to be installed, and most steps will create a virtualenv
+(``doc_venv``) which install the documentation generation toolset.
+
+Run ``make html`` to generate html documentation in ``_build/html``.
+
+Run ``make reload`` to get a live reload in your browser (refreshes on document
+save).
+
+To check the formatting of documentation, run ``make lint``. This will be done
+in Jenkins to validate the documentation, so please do this before you create a
+patchset.
+
+Writing Docs
+------------
+
+Docs written using sphinx: http://www.sphinx-doc.org
+
+Documentation is done in reStructuredText (``.rst``)  or Markdown (``.md``),
+but only .rst files can use certain features like embedded diagrams.
+
+reStructuredText Primer:
+http://www.sphinx-doc.org/en/master/usage/restructuredtext/index.html
+
+Creating Diagrams
+-----------------
+
+Inline Graphviz is supported:
+https://www.sphinx-doc.org/en/master/usage/extensions/graphviz.html
+
+The blockdiag suite of tools can be used for other specific graph types:
+
+- Block diagrams: http://blockdiag.com/en/blockdiag/sphinxcontrib.html
+- Network diagrams (& racks): http://blockdiag.com/en/nwdiag/sphinxcontrib.html
+
+Attributes that can be applied to nodes:
+http://blockdiag.com/en/blockdiag/attributes/node.attributes.html
+
+Examples:
+
+- blockdiag: http://blockdiag.com/en/blockdiag/examples.html
+- nwdiag: http://blockdiag.com/en/nwdiag/nwdiag-examples.html
+- rackdiag: http://blockdiag.com/en/nwdiag/rackdiag-examples.html
