I sent a pull request to Rails today and it was merged after a bit fix. Yay! I’m now one of the Rails contributors!

http://contributors.rubyonrails.org/contributors/kentaro-kuribayashi/commits

It was just one line patch that fixes a potential error on Bundler <= 1.2.1 and Ruby 2.0.0. For details, please check out the pull request.

I wanna contribute to Rails by implementing more important features next time 😉
