All developers are different, and this is why the Slim Framework project has contributor guidelines. These ensure all contributors follow the same rules and the same code style.
Separate each new feature or improvement into a separate branch in your forked repository.
Submit a pull request from each feature branch to the Slim Framework repository's
branch. All changes should include appropriate PHPUnit tests.
