+Sideshow
+========
+
+This is a web app which provides retailers a way to track case/special
+orders.
+
+Good documentation and 100% `test coverage`_ are priorities for this
+project.
+
+.. _test coverage: https://buildbot.rattailproject.org/coverage/sideshow/
+
+However as you can see..the API should be fairly well documented but
+the narrative docs are pretty scant.  That will eventually change.
