+# start-ozone environment
+
+This is an example environment to use/test `./sbin/start-ozone.sh` and `./sbin/stop-ozone.sh` scripts.
+
+There are ssh connections between the containers and the start/stop scripts could handle the start/stop process
+similar to a real cluster.
+
+To use it, first start the cluster:
+
+```
+docker-copmose up -d
+```
+
+After a successfull startup (which starts only the ssh daemons) you can start ozone:
+
+```
+./start.sh
+```
+
+Check it the java processes are started:
+
+```
+./ps.sh
+```
