+	<description>
+		<p>
+			micro is a terminal-based text editor that aims to be easy to use and
+			intuitive, while also taking advantage of the capabilities of modern terminals.
+			It comes as a single, batteries-included, static binary with no dependencies;
+			you can download and use it right now!
+		</p>
+		<p>
+			As its name indicates, micro aims to be somewhat of a successor to the nano
+			editor by being easy to install and use. It strives to be enjoyable as a full-time
+			editor for people who prefer to work in a terminal, or those who regularly
+			edit files over SSH.
