-ejabberd - High-Performance Enterprise Instant Messaging Server 
----------------------------------------------------------------
+Ejabberd Community Edition, by ProcessOne
+-----------------------------------------
 
-Quickstart guide
-================
+
+ejabberd is a distributed, fault-tolerant technology that allows the creation
+of large-scale instant messaging applications.
+The server can reliably support thousands of simultaneous users on a single
+node and has been designed to provide exceptional standards of fault
+tolerance.
+As an open source technology, based on industry-standards, ejabberd can be
+used to build bespoke solutions very cost effectively.
+
+
+Key Features:
+=============
+
+
+-   Cross-platform: ejabberd runs under Microsoft Windows and Unix derived
+systems such as Linux, FreeBSD and NetBSD.
+-   Distributed: You can run ejabberd on a cluster of machines and all of them
+will serve the same Jabber domain(s). When you need more capacity you can
+simply add a new cheap node to your cluster. Accordingly, you do not need to
+buy an expensive high-end machine to support tens of thousands concurrent
+users.
+-   Fault-tolerant: You can deploy an ejabberd cluster so that all the
+information required for a properly working service will be replicated
+permanently on all nodes. This means that if one of the nodes crashes, the
+others will continue working without disruption. In addition, nodes also can
+be added or replaced ‘on the fly’.
+-   Administrator Friendly: ejabberd is built on top of the Open Source
+Erlang. As a result you do not need to install an external database, an
+external web server, amongst others because everything is already included,
+and ready to run out of the box. Other administrator benefits include: 
+        Comprehensive documentation.
+        Straightforward installers for Linux, Mac OS X.
+        Web Administration.
+        Shared Roster Groups.
+        Command line administration tool.
+        Can integrate with existing authentication mechanisms.
+        Capability to send announce messages._
+-   Internationalized: ejabberd leads in internationalization. Hence it is
+very well suited in a globalized world. Related features are:
+        Translated to 25 languages.
+        Support for IDNA._
+-   Open Standards: ejabberd is the first Open Source Jabber server claiming
+to fully comply to the XMPP standard.
+        Fully XMPP compliant.
+        XML-based protocol.
+        Many protocols supported._
+
