Gittribute saves your time on getting help on your open-source project. Need help on your project? All you need is to add one line on your Github project's README.md & click your link there, and then everyone in the world will see you need help and they will find you.

I want to post a screenshot, but currently there is only one project listed on the website, so may be it is better if those interested care to check the website itself: http://gittribute.herokuapp.com/
