-		Mangowm(formerly maomaowm/mangowc) is a Wayland compositor, forked from dwl.
-
-		Mangowm supports customizable complete animations, flexible window layouts
-		(scroller, dwindle, master, etc.), rich window states, scratchpads,
-		window effects and powerful external configuration with live reloading.
+	<longdescription>
+		Mango starts where dwl ends. It keeps the lightweight, fast-build
+		philosophy while adding the features that make a compositor actually
+		usable day-to-day — without the bloat.
