Contributing Guidelines

Fork the project.
Make your feature addition or bug fix.
Add tests for it. This is important so I don't break it in a future version unintentionally.
Commit just the modifications, do not mess with the composer.json or CHANGELOG.md files.
Ensure your code is nicely formatted in the PSR-2 style and that all tests pass.
Send the pull request.
Check that the Travis CI build passed. If not, rinse and repeat.
