+# commitbot
+
+Commitbot is an XMPP bot that notifies multi-user chat rooms (MUCs) of
+git repository commits.
+
+It uses the [GitHub](http://www.github.com) post-receive web hook to
+get push notifications of repository changes.
+
+## Dependencies
+
+* [Twisted](http://www.twistedmatrix.com) 8.1.x or later
+* [Wokkel](http://wokkel.ik.nu) 0.4 or later
+* [simplejson](http://pypi.python.org/pypi/simplejson)
+
+Note that on Ubuntu/Debian systems Twisted is split into various
+pieces.  You will want:
+
+* python-twisted-words
+* python-twisted-names
+
+in addition to the normal Twisted package.
+
+## Usage
+
+Copy `commitbot.tac.example` to `commitbot.tac` changing the JID,
+password, room name, and room nickname to something appropriate.  Then
+launch it with `twistd`.
+
+    twistd -y commitbot.tac
