Description
===========
-**ceph** is a control utility for communicating with the monitor
-cluster of a running Ceph distributed storage system.
+**ceph** is a control utility which is used for manual deployment and maintenance
+of a Ceph cluster. It provides a diverse set of commands that allows deployment of
+monitors, OSDs, placement groups, MDS and overall maintenance, administration
+of the cluster.
