+    (description "Kigo is an open-source implementation of the popular Go
+game.
+
+Go is a strategic board game for two players.  It is also known as
+igo (Japanese), weiqi or wei ch'i (Chinese) or baduk (Korean).  Go is noted
+for being rich in strategic complexity despite its simple rules.  The game is
+played by two players who alternately place black and white stones (playing
+pieces, now usually made of glass or plastic) on the vacant intersections of a
+grid of 19x19 lines (9x9 or 13x13 for easier games).
+
+You also need to install a go engine, e.g. @code{gnugo}.
