+Qt Labs Controls
 ================
+
+The Qt Labs Controls module is a technology preview of the next generation
+user interface controls based on Qt Quick. In comparison to the desktop-
+oriented Qt Quick Controls 1, the experimental Qt Labs Controls are an order
+of magnitude simpler, lighter and faster, and are primarily targeting embedded
+and mobile platforms.
