Hi guys!

First of all thank you for open sourcing Ele, it is teaching me so much about polymer and how to create a jsfiddle-like app with it.

Could you specify in your REAME that in order to start Ele you have to create an application in Github and enter http://localhost:3000/auth/callback in the Authorization callback URL field. It would save the reader a couple of greps and google searches.

Regards,
Julian
