Branches organization:

master - is the main branch, only used to merge in a "final release"
development - is the branch where the development of the "next" version/s happens
release-2.1 - is the branch where bug fixes for the version 2.1 are applied

How to contribute:

fork the repository. If you are not used to Github, please check out fork a repository.
branch your repository, to commit the desired changes.
sign-off your commits, to acknowledge your submission under the license of the project.

How to submit a pull request:

If you want to send a bug fix for the version 2.1, send it to the branch release-2.1

You should never send any pull request against the master branch For more information, the ideal branching we would like to follow is the one described in this article
