The resulting image can be run as a standalone container. It will expose
ports for all of the services provided by Citadel Server, and two instances
of WebCit (HTTP and HTTPS).
+
+Use the "run-citadel.sh" script to start the container, or use it to learn
+what information needs to be supplied. In particular, you need to map a
+persistent volume to the data directory, otherwise you will lose all of your
+data when the container is upgraded.
