Contributing ============ First of all, **thank you** for contributing, **you are awesome**! Here are a few rules to follow in order to ease code reviews, and discussions before maintainers accept and merge your work. You MUST follow some coding standard rules, like [PSR-1](http://www.php-fig.org/psr/1/) and [PSR-2](http://www.php-fig.org/psr/2/). Fortunately, you can automate the fixing for that rules, using [PHP-CS-Fixer](https://github.com/FriendsOfPHP/PHP-CS-Fixer) tool. There is a configuration file included in this repository, named `.php_cs`. You MUST run the test suite. You MUST write (or update) unit tests. Please, write [commit messages that make sense](http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html), and [rebase your branch](http://git-scm.com/book/en/Git-Branching-Rebasing) before submitting your Pull Request. Thank you!
