Couple of requests

1. Add comments

There's a lot going on here and very few comments

2. In the README point out the entry point of the code

There are a lot of places one could start reading, give users a hint as to the best place to start.

Your app template.html points toward a /js/app.js file which doesn't exist in the source, which is fine, but if I'd like to read before I run a pointer would be helpful!
