 ## That's it
 
 Just run `engine.update(dt)` in your game loop :D
 
-## Checking it in the frontend (dev).
-
-You can link the bower package to test it out locally.
-Spawn a python server (`python -m SimpleHTTPServer`) to see
-the test page in `http://localhost:8000/browser_test/`

 ## TO-DO
 
-* Removing components
-* Implement the ashteroids demo (Serpentoids)
-* Actually check performance
+* Minimize code (Uglify does not support ES6 yet)
+* Check Performance
