+Kolab Integration Plugin README
+-------------------------------
+
+This plugin relies on classes from the Horde project. In order to have all
+the required files available you need to install the following packages from
+Horde:
+	Horde_Framework
+	Kolab_Format
+	Kolab_Storage
+	Horde_NLS
+	Horde_DOM
+
+This is best done using PEAR. Make sure that the local PEAR directory is in
+the PHP isntall path and execute the following commands to install the
+required packages:
+
+pear channel-discover pear.horde.org
+
+pear install horde/Horde_Framework
+pear install horde/Horde_DOM
+pear install horde/Horde_NLS
+pear install horde/Horde_Share
+pear install horde/Log
+pear install horde/Kolab_Format
+pear install horde/Kolab_Storage
+
+
+Configuration
+-------------
+
+Rename the config.inc.php.dist to config.inc.php within this plugin directory
+and add the corresponding values for your local Kolab server.
