+Armstrong Sphinx Theme
+======================
+Sphinx theme for Armstrong documentation
+
+
+Usage
+-----
+Symlink this repository into your documentation at ``docs/_themes/armstrong``
+then add the following two settings to your Sphinx ``conf.py`` file::
+
+    html_theme = "armstrong"
+    html_theme_path = ["_themes", ]
+
+You can also change colors and such by adjusting the ``html_theme_options``
+dictionary.  For a list of all settings, see ``theme.conf``.
+
+
+Defaults
+--------
+This repository has been customized for Armstrong documentation, but you can
+use the original default color scheme on your project by copying the
+``rtd-theme.conf`` over the existing ``theme.conf``.
+
+
+Contributing
+------------
+
+* Create something awesome -- make the code better, add some functionality,
+  whatever (this is the hardest part).
+* `Fork it`_
+* Create a topic branch to house your changes
+* Get all of your commits in the new topic branch
+* Submit a `pull request`_
+
+.. _Fork it: http://help.github.com/forking/
+.. _pull request: http://help.github.com/pull-requests/
+
+
+State of Project
+----------------
+Armstrong is an open-source news platform that is freely available to any
+organization.  It is the result of a collaboration between the `Texas Tribune`_
+and `Bay Citizen`_, and a grant from the `John S. and James L. Knight
+Foundation`_.  The first stable release is scheduled for September, 2011.
+
+To follow development, be sure to join the `Google Group`_.
+
+``armstrong_sphinx`` is part of the `Armstrong`_ project.  Unless you're
+looking for a Sphinx theme, you're probably looking for the main project.
