 This plugin provides a unified experience for checkers (CI systems, static
 analyzers, etc.) to integrate with Gerrit Code Review.
+
+This plugin uses [polymer-cli](https://www.polymer-project.org/1.0/docs/tools/polymer-cli#install) to test.
+
+After `bower install`, running `polymer test -l chrome` will run all tests in Chrome, and running `polymer serve` and navigating to http://127.0.0.1:8081/components/checks/gr-checks/gr-checks-view_test.html allows for manual debugging.
