       This starts each instance as a member of a replica set named
       ``rs0``, each running on a distinct port. If you are already using
-      these ports, you can select different ports. See the documentation
-      of the following options for more information: :option:`--port
-      <mongod --port>`, :option:`--dbpath <mongod --dbpath>`, and
-      :option:`--replSet <mongod --replSet>`.
+      these ports, select different ports.
+
+      The :setting:`smallfiles` and :setting:`oplogSize`
+      options are used for testing, not for production, and
+      reduce the disk space that each
+      :program:`mongod` uses. For more information on these and other
+      configuration options, see
+      :doc:`/reference/configuration-options`.
