+Running The Server
+----
+Elasticsearch and MongoDB servers need to be available, and correctly referenced
+in config/application.yml and config/mongoid.yml, respectively.
+
+Before the server is first run, ensure gems are installed by doing ``bundle install``.
+
+To run the server, do ``ruby app.rb [-p PORT]`` where PORT defaults to 4567.
+
+If you are running cs_comments_service as part of edx-platform__ development under
+devstack, it is strongly recommended to read `those setup documents`__ first.  Note that
+devstack will take care of just about all of the installation, configuration, and 
+service management on your behalf.

+for additional options to this command.
