This package is already part of rector/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:

composer require rector/rector --dev

Use Sets

To add a set to your config, use Rector\Set\ValueObject\DowngradeLevelSetList class and pick target set:

use Rector\Set\ValueObject\DowngradeLevelSetList;
use Rector\Config\RectorConfig;

return static function (RectorConfig $rectorConfig): void {

Then run Rector to downgrade your code to PHP 7.2!
