+  <p>
+   GNOME Chess is a simple chess game. You can play against your computer at
+   three different difficulty levels, or against a friend at your computer.
+  </p>
+  <p>
+  Computer chess enthusiasts will appreciate GNOME Chess's compatibility with
+  nearly all modern computer chess engines, and its ability to detect several
+  popular engines automatically if installed.
