+cephadm bootstrap --shared_ceph_folder
+======================================
+
+Cephadm can also be used directly without compiled ceph binaries.
+
+Run cephadm like so::
+
+  sudo ./cephadm bootstrap --mon-ip 127.0.0.1 \
+    --ssh-private-key /home/<user>/.ssh/id_rsa \
+    --skip-mon-network \
+    --skip-monitoring-stack --single-host-defaults \
+    --skip-dashboard \ 
+    --shared_ceph_folder /home/<user>/path/to/ceph/
+
+- ``~/.ssh/id_rsa`` is used as the cluster key.  It is assumed that
+  this key is authorized to ssh with no passphrase to root@`hostname`.
+
+Source code changes made in the ``pybind/mgr/`` directory then
+require a daemon restart to take effect. 
+
 Note regarding network calls from CLI handlers
