Contribute to a project 
If you want to contribute to a project and make it better, your help is very welcome. Contributing is also a great way to learn more about social coding on Github, new technologies and and their ecosystems and how to make constructive, helpful bug reports, feature requests and the noblest of all contributions: a good, clean pull request.

How to make a clean pull request
Look for a project's contribution instructions. If there are any, follow them.

Create a personal fork of the project on Github.
Clone the fork on your local machine. Your remote repo on Github is called origin.
Add the original repository as a remote called upstream.
If you created your fork a while ago be sure to pull upstream changes into your local repository.
