just want to ask what provider to add? twitter, facebook, github?

Anything is fine since the implementation is still the same. I suggest following this Railscasts episode to implement this feature. If you don't have a Railscasts pro account, let me know, so I can provide you with the video.

please check #18 pull request since I can't attach it here 👊

Oh, right. I forgot to mention this earlier, but you can actually attach your pull request to an existing issue by using hub, a tool for making Git easier to use with GitHub's APIs. Here's a StackOverflow discussion about your problem.

It's fine that you weren't able to do this with your current pull request. This is just an FYI for your upcoming pull requests to this or other projects you might work on in the future.
