 ## What is Pacemaker?
 
-Pacemaker is an advanced, scalable high-availability cluster resource manager.
-
-It supports "N-node" clusters with significant capabilities for
-managing resources and dependencies.
-
-It will run scripts at initialization, when machines go up or down,
-when related resources fail and can be configured to periodically check
-resource health.
+Pacemaker is the resource manager for the
+[ClusterLabs](https://www.clusterlabs.org/) open-source high-availability
+cluster stack. It coordinates the configuration, start-up, monitoring, and
+recovery of interrelated services across all cluster nodes.
 
 ## Who is Pacemaker?
 
-Pacemaker is distributed by [ClusterLabs](https://www.clusterlabs.org/).
-
 Pacemaker was initially created by main architect and lead developer
-Andrew Beekhof <[email protected]>, with the aid of
+Andrew Beekhof <[email protected]> with the aid of
 project catalyst and advocate Lars Marowsky-Brée <[email protected]>.
 
 Many, many developers have contributed significantly to the project since.
 The git log is the definitive record of their greatly appreciated
 contributions.
 
-The wider community of Pacemaker users is another essential aspect of the
-project's existence, especially the many users who participate in the mailing
-lists, blog about HA clustering, and otherwise actively make the project more
-useful.

-## What higher-level interfaces to Pacemaker are available?
-
-There are multiple user interfaces for Pacemaker, including command-line
-tools, graphical user interfaces and web frontends. The crm shell
-used to be included in the Pacemaker source tree, but is now
-a separate project.

-### Can I convert some other cluster configuration to Pacemaker?
-
-[clufter](https://github.com/jnpkrn/clufter) is a general-purpose tool
-for converting one cluster representation format to another. Among other
-possibilities, it can convert from a cluster based on rgmanager with CMAN to
-a one based on pacemaker with corosync. See its documentation for details.
