+# Zuul: Project Gating for Gerrit
+
+Zuul is a project gating system, which is like a CI/CD system that is
+primarily focused on ensuring multiple changes are well-tested with
+each other before being merged.
+
+Zuul was originally written for Gerrit, and as such, has a special
+relationship with it.  Zuul takes advantage of Gerrit topics to
+support circular dependencies between changes.  It may be the only CI
+system that can do something reasonable with Gerrit submodule
+subscriptions.  And it recently added its eighth method of interfacing
+with Gerrit.
+
+In addition to all this love for Gerrit, Zuul also seamless integrates
+with other code review systems allowing teams to use its cross-project
+dependency features to test changes in Gerrit and GitHub/Gitlab/etc
+together.
+
+This presentation will provide an overview of Zuul, how it integrates
+with Gerrit, and recent updates to support new features in Gerrit.
