 ## Launching a container set
 
 Pick out a simple container set and launch it as follows:
 
-docker-compose -f compose/rabbitmq.yml up -d
+    $ docker-compose -f compose/rabbitmq.yml up -d
 
 The third party deployment engine should launch the appropriate containers for
-the appropriate nodes.  Note the rabbitmq.yml used in the example above expects
-an openstack.env file present in the current working directory.  This file will
-be passed as environment data to the container and configure the container
-appropriately.

 # Conclusion
 
-Integrating with Kolla is as sample as creating an openstack.env file, having
-a deployment tool write the openstack.env file and .yml files to the nodes
-are targeted for deployment, and running docker-compose as described in the
-above documentation.
