+====================
+ Package Management
+====================
+
+Install
+=======
+
+To install Ceph packages on your cluster hosts, open a command line on your
+client machine and type the following::
+
+       ceph-deploy install {hostname [hostname] ...}
+
+Without additional arguments, ``ceph-deploy`` will install the most recent
+stable Ceph package to the cluster host(s). To specify a particular package, 
+you may select from the following:
+
+- ``--stable <code-name>`` 
+- ``--testing`` 
+- ``--dev <branch-or-tag>`` 
+
+For example:: 
+
+       ceph-deploy install --stable <code-name> <hostname1 [hostname2] ...>
+       ceph-deploy install --stable bobtail hostname{1,2,3,4,5}
+       ceph-deploy install --testing hostname1
+       ceph-deploy install --dev wip-some-branch hostname{1,2,3,4,5}
+       
+For additional details, see `Installing Debian/Ubuntu Packages`_.
+For additional usage, execute:: 
+
+       ceph-deploy install -h
+
+
+Uninstall
+=========
+
+To uninstall Ceph packages from your cluster hosts, open a commandline on 
+your admin host and type the following:: 
+
+       ceph-deploy uninstall {hostname [hostname] ...}
+
+The tool will unininstall ``ceph`` packages from the specified hosts. Other
+commands may also invoke ``ceph-deploy uninstall``, such as ``purge``.
