-If you would like to contribute, here are some notes and guidlines:

- - The master branch only contains tagged releases
- - If you are going to be submitting a pull request, please fork from 1.8, and submit your pull request back to that 1.8 branch
- - Wherever possible, code changes should conform as closely as possible to PSR-2 standards
- - [Helpful article about forking](https://help.github.com/articles/fork-a-repo/ "Forking a Github repository")
- - [Helpful article about pull requests](https://help.github.com/articles/using-pull-requests/ "Pull Requests")
