  Installation
 ==============
 
-Storage clusters are the foundation of the Ceph system. Ceph storage hosts
-provide object storage. Clients access the Ceph storage cluster directly from
-an application (using ``librados``), over an object storage protocol such as
-Amazon S3 or OpenStack Swift (using ``radosgw``), or with a block device
-(using ``rbd``). To begin using Ceph, you must first set up a storage cluster.
+The Ceph Object Store is the foundation of all Ceph clusters, and it consists
+primarily of two types of daemons: Object Storage Daemons (OSDs) and monitors.
+The Ceph Object Store is based upon the concept of 
+:abbr:`RADOS (Reliable Autonomic Distributed Object Store)`, which eliminates
+single points of failure and delivers infinite scalability. For details on 
+the architecture of Ceph and RADOS, refer to `Ceph Architecture`_. All Ceph
+deployments have OSDs and monitors, so you should prepare your Ceph cluster
+by focusing first on the object storage cluster.
 
-You may deploy Ceph with our ``mkcephfs`` bootstrap utility for development
-and test environments. For production environments, we recommend deploying 
-Ceph with the Chef cloud management tool.

-If your deployment uses OpenStack, you will also need to install OpenStack.

-The following sections provide guidance for installing components used with
-Ceph:

+       
+To begin using Ceph in production, you should review our hardware
+recommendations and operating system recommendations. Many of the
+frequently-asked questions in our mailing list involve hardware-related
+questions and how to install Ceph on various distributions.

+
+If you are deploying a Ceph cluster (that is, not developing Ceph),
+install Ceph using our stable release packages. For testing, you 
+may install development release and testing packages. If you intend
+to deploy Ceph using OpsCode Chef, review the instructions for 
+Chef below. 
+       
+.. tip:: If you are using Dell Crowbar, or Ceph-Deploy you do not 
+       need to install OpsCode Chef.

+
+You can build Ceph from source by downloading a release or cloning the ``ceph``
+repository at github. If you intend to build Ceph from source, please see the
+build pre-requisites first. Making sure you have all the pre-requisites
+will save you time.
