+	<description>
+		<p>
+			Nagstamon is a status monitor for the desktop. It connects to multiple Nagios, Icinga, Opsview, Centreon,
+			Op5 Monitor/Ninja, Check_MK Multisite and Thruk monitoring servers. It resides in systray, as a floating
+			statusbar or fullscreen at the desktop showing a brief summary of critical, warning, unknown, unreachable
+			and down hosts and services. It pops up a detailed status overview when being touched by the mouse pointer.
+			Connections to displayed hosts and services are easily established by context menu via SSH, RDP, VNC or
+			any self defined actions. Users can be notified by sound. Hosts and services can be filtered by category
+			and regular expressions.
