+ <description>
+  <_p>
+   Play the highly addictive 2048 game. GNOME 2048 is a clone of the popular
+   single-player puzzle game. Gameplay consists of joining numbers in a grid
+   and obtain the 2048 tile.
+  </_p>
+  <_p>
+   Use your keyboard's arrow keys to slide all tiles in the desired direction.
+   Be careful: all tiles slide to their farthest possible positions, you cannot
+   slide just one tile or one row or column. Tiles with the same value are
+   joined when slided one over the other.
+  </_p>
+  <_p>
+   With every new tile obtained you increase your score. If you think you can easily
+   get the 2048 tile, do not let it stop you, the game does not end there, you can
+   continue joining tiles and improving your score.
+  </_p>
+  <_p>
+   Originally created by Gabriele Cirulli, 2048 has gained much popularity
+   due to it being highly addictive. Cirulli's 2048 is in turn a clone of
+   the 1024 game and includes ideas from other clones.
