+    <item>
+      <p>Open the application menu in the top bar and select
+      <guiseq><gui style="menuitem">Preferences</gui>
+      <gui style="menuitem">Game</gui></guiseq>.</p>
+    </item>
+    <item>
+      <p>Under <gui>Opposing player</gui>, choose
+      <gui style="radiobutton">Human</gui> for both players if want to play
+      with a friend or family member.</p>
+      <p>Alternatively, choose a different chess engine. The list depends on
+      the chess engines installed on your system.
