+## Running a development instance locally
+
+`RegistryTestServer` is a lightweight test server for the registry that is
+suitable for running locally for development.  It uses local versions of all
+Google Cloud Platform dependencies, when available.  Correspondingly, its
+functionality is limited compared to a Domain Registry instance running on an
+actual App Engine instance.  To see its command-line parameters, run:
+
+    $ bazel run //javatests/google/registry/server -- --help
+
+Then to fire up an instance of the server, run:
+
+    $ bazel run //javatests/google/registry/server {your params}
+
+Once it is running, you can interact with it via normal `registry_tool`
+commands, or view the registrar console in a web browser by navigating to
+http://localhost:8080/registrar .
