 ## Coding Standards & Static Analysis
 
 When contributing code to PHP-ML, you must follow its coding standards. To do that, just run:
 
 ```bash
-vendor/bin/ecs check src tests --fix
+composer fix-cs
 ```
 [More about EasyCodingStandard](https://github.com/Symplify/EasyCodingStandard)
 
 Code has to also pass static analysis by [PHPStan](https://github.com/phpstan/phpstan):
 
 ```bash
-vendor/bin/phpstan.phar analyse src tests --level max --configuration phpstan.neon
+composer phpstan
 ```
