+<p>
+	If you use a skybox, the engine will look in the <i>textures/sky</i> directory for six images named
+	<i>skybox_up</i>, <i>skybox_down</i>, <i>skybox_left</i>, <i>skybox_right</i>, <i>skybox_front</i> and <i>skybox_back</i>.
+	The coordinates are setup to match the output of the <A href="http://alexcpeterson.com/spacescape">Spacescape</a> skybox generator
+</p>
+<p>
+	If you want to use skyboxes made for quake3 you will have to convert them:
+<ul>
+	<li>The _left and _right images have to be swapped
+	<li>The _up image has to be rotated, 90 degrees clockwise
+	<li>The _down image has to be rotated, 90 degrees counter-clockwise
+</ul>
