+ceph-deploy
+-----------
+
+The ceph-deploy tool is now the preferred method of provisioning new
+clusters.  For existing clusters created via mkcephfs that would like
+to transition to the new tool, there is a migration path, documented
+at `Transitioning to ceph-deploy`_.  Note that transitioning to
+ceph-deploy is not required; it is entirely acceptable to continue
+provisioning new OSDs and monitors using the previous methods.
+However, ceph-deploy streamlines these processes significantly.
