+## Dim
+
+A tiny menubar Mac app for multi-monitor users. Automatically dims your secondary screen when you start fullscreen video. You can see it in action in the [demo video](http://www.youtube.com/watch?v=yVGFIJ6b34c&feature=youtu.be). Now open-sourced and compatible with Yosemite.
+
+### Tested on
+- OS X 10.9.x + Safari 7 + Firefox
+- OS X 10.10 DP3 + Safari 8
+
+Should work on 10.8 too!
+
+No Chrome support at the moment, blame Google for their useless AppleScript Chrome API.
