# Rector Rules for PHPParser See available [PHPParser rules](/docs/rector_rules_overview.md) ## Install This package is already part of [rector/rector](http://github.com/rectorphp/rector) package, so it works out of the box. All you need to do is install the main package, and you're good to go: ```bash composer require rector/rector --dev ``` ## Use Sets To add a set to your config, use `Rector\PhpParser\Set\PhpParserSetList` class and pick one of constants: ```php use Rector\PhpParser\Set\PhpParserSetList; use Rector\Config\RectorConfig; return static function (RectorConfig $rectorConfig): void { $rectorConfig->sets([ PhpParserSetList::PHP_PARSER_50 ]); }; ```
