# Coding Style
Code style must follow PSR-1 (opens new window), PSR-2 (opens new window) and PSR-12 (opens new window).
Generally speaking, everything string-like that's not public-facing should use camelCase. Detailed examples on these are spread throughout the guide in their relevant sections.
To maintain consistent coding style we use PHP CS Fixer with predefined ruleset.
For detailed information on coding style ruleset, take a look into .php-cs-fixer.php on project's root directory.
To automatically fix any coding style violations, run:
sail composer cs-fixer
