 Thank you for trying Ceph! We recommend setting up a ``ceph-deploy`` admin
 :term:`node` and a 3-node :term:`Ceph Storage Cluster` to explore the basics of
-Ceph. This **Preflight Checklist** will help you prepare a ``ceph-deploy`` admin
-node and three Ceph Nodes (or virtual machines) that will host your Ceph Storage
-Cluster. Before proceeding any further, see `OS Recommendations`_ to verify that
