+Fonts
+=====
+
+Fonts are defined like so:
+
+```
+<fontTag>
+	<path>./path/to/font</path>
+	<size>0.05</size>
+</fontTag>
+```
+
+You can leave off any tags you don't want to use, and they'll use the default. Size is defined as a percentage of the screen height. "." and "~" are expanded for paths.
+
+**Font tags:**
+
+`<listFont>` - font to use for the game list.
+
+`<descriptionFont>` - font to use for description text.
