+Zuul - A Project Gating System
+==============================
+
+Zuul is a program that is used to gate the source code repository of a
+project so that changes are only merged if they pass tests.
+
+The main component of Zuul is the scheduler.  It receives events
+related to proposed changes (currently from Gerrit), triggers tests
+based on those events (currently on Jenkins), and reports back.
