-You may use the [PHP-CS-Fixer](https://github.com/FriendsOfPHP/PHP-CS-Fixer) to fix your code style before committing.
-
-To get started, [install the tool globally](https://github.com/FriendsOfPHP/PHP-CS-Fixer#globally-manual) and check the code style by issuing the following terminal command from your project's root directory:
-
-```sh
-php-cs-fixer fix
-```
+Don't worry about getting your code style perfect, since [StyleCI](https://styleci.io/) will automatically merge any fixes into our codebase after we merge external contributions. This way, we can focus on the content of the contribution, and not the code style.
