 ### Secondary Index with Elastic Search
 
+### New User Interface ("PolyGerrit")
+
+Gerrit now includes a new user interface, referred to as "PolyGerrit", based on
+[Polymer](https://www.polymer-project.org/).
+
+The UI can be switched between PolyGerrit and GWT by clicking the "New UI" and
+"Old UI" links in the site footer. Alternatively, the UI can be switched by
+adding `?polygerrit=1` or `?polygerrit=0` to the URL.
+
+Note that PolyGerrit is still under development. Most use cases are supported,
+but there are still some missing features compared to the GWT UI.
