 Cephadm
 =======
 
-Cephadm deploys and manages a Ceph cluster by connection to hosts from the
-manager daemon via SSH to add, remove, or update Ceph daemon containers.  It
-does not rely on external configuration or orchestration tools like Ansible,
-Rook, or Salt.
-
-Cephadm manages the full lifecycle of a Ceph cluster.  It starts
-by bootstrapping a tiny Ceph cluster on a single node (one monitor and
-one manager) and then uses the orchestration interface ("day 2"
-commands) to expand the cluster to include all hosts and to provision
-all Ceph daemons and services.  This can be performed via the Ceph
-command-line interface (CLI) or dashboard (GUI).
