+HTTP API. The integration tests can start a local instance of the
+controller; either of the following works:
+
+    ./check
+    ./check local

+You can add any command line parameters `yarn` accepts, but you have
+to specify `local` explicitly:
+
+    ./check local -v --tempdir tmp --snapshot
+
+You can also run the integration tests against an existing remote

+    ./check https://ick-controller
+    ./check https://ick-controller -v --tempdir tmp --snapshot
+
+Please make sure at least the local `./check` passes with your
+changes, before submitting them.
