[yeashinr]

Please let me merge.

Looks great! But there does appear to be some conflict in the src/index.js. Could you please try to rebase your changes onto master and resolve those?

[yeashinr]

I have resolved the issues that you mentioned. But, not sure about the conflicting one. I rebase onto master. Not sure whether it solves the issue or not.

[kentcdodds]

There are still conflicts, but I can fix those for you no problem :) I'm not sure what happened.

Looks great!
