+Introduction
+------------
+
+The Scope of This Document
+##########################
+
+Computer clusters can be used to provide highly available services or
+resources. The redundancy of multiple machines is used to guard
+against failures of many types.
+
+This document will walk through the installation and setup of simple
+clusters using the |CFS_DISTRO| distribution, version |CFS_DISTRO_VER|.
+
+The clusters described here will use Pacemaker and Corosync to provide
+resource management and messaging. Required packages and modifications
+to their configuration files are described along with the use of the
+``pcs`` command line tool for generating the XML used for cluster
+control.
+
+Pacemaker is a central component and provides the resource management
+required in these systems. This management includes detecting and
+recovering from the failure of various nodes, resources, and services
+under its control.
+
+When more in-depth information is required, and for real-world usage,
+please refer to the `Pacemaker Explained <https://www.clusterlabs.org/pacemaker/doc/>`_
+manual.
