+# Classic Desktop Icons
+
+This mod will enable classic theme on desktop icons when themes are enabled,
+and will optionally let you restore the Windows 2000 behavior of rendering
+the desktop color on the items' labels.
+
+## For label backgrounds to show, you must DISABLE desktop icon label shadows.
+
+## Screenshots
+
+**Windows XP style (shadows, no label backgrounds)**:
