+
+> **Note**: Run `make` or `make help` to see all available commands.

 ## Standard code
 
 Use [PHP CS fixer](http://cs.sensiolabs.org/) to make your code compliant with
 Memio's coding standards:
 
 ```console
-$ ./vendor/bin/php-cs-fixer fix .
+make cs-fix
 ```
 
 ## Specifications

 First bootstrap the code for the Specification:

 Next, write the actual code of the Specification:
