+============================
+Welcome To The DXR Community
+============================
+
+Though DXR got its start at Mozilla, it's seen contributions from a variety of
+companies, individuals, and places around the world. We welcome contributions
+of code, bug reports, and helpful feedback.
+
+
+Bug Reports
+===========
+
+Did something explode? Not act as you expected? `Let us know
+<https://bugzilla.mozilla.org/enter_bug.cgi?product=Webtools&component=DXR>`__.
+
+
+Submitting Patches
+==================
+
+To contribute code, just file a `pull request
+<https://github.com/mozilla/dxr/compare/>`__. Include tests to double your
+chances of getting it merged and qualify for a free Bundt cake. We love tests.
+Bundt cake isn't bad, either.
+
+
+IRC
+===
+
+We hang out in the #static channel of irc.mozilla.org. Poke your head in, and
+say hello.
+
+
+Open Bugs
+=========
+
+Looking for something to hack on? Here are...
+
+* `Our easy bugs <https://bugzilla.mozilla.org/buglist.cgi?quicksearch=whiteboard%3Aeasy%20component%3ADXR&list_id=6127603>`__
+* `All our bugs <https://bugzilla.mozilla.org/buglist.cgi?order=Importance&resolution=---&query_format=advanced&component=DXR&product=Webtools>`__
+
+Before starting work on a bug, hop into the IRC channel and confirm it's still
+relevant. We try to garden our bugs, but DXR often moves faster than we can
+weed.
+
+
+Wiki
+====
+
+The `wiki <https://wiki.mozilla.org/DXR>`__ is full of roadmap documents,
+sketches toward future features, and bikeshedding sessions. Feel free to
+scribble on it.
