+Kolla ships with several utilities intended to facilitate ease of operation.
+
+``tools/cleanup-containers`` can be used to remove deployed containers from
+the system. This can be useful when you want to do a new clean deployment. It
+will preserve the registry and the locally built images in the registry,
+but will remove all running Kolla containers from the local Docker daemon.
+It also removes the named volumes.
+
+``tools/cleanup-host`` can be used to remove remnants of network changes
+triggered on the Docker host when the neutron-agents containers are launched.
+This can be useful when you want to do a new clean deployment, particularly
+one changing the network topology.
+
+``tools/cleanup-images`` can be used to remove all Docker images from the
+local Docker cache. Note: this will remove the registry also.
