+```php
+use Symfony\Component\DependencyInjection\Loader\Configurator\ContainerConfigurator;
+use Symplify\Skipper\ValueObject\Option;

+return static function (ContainerConfigurator $containerConfigurator): void {

+        SomeSniff::class . '.SomeCode' => ['*Sniff.php', '*YamlFileLoader.php'],
+    ]);
+};
+```

+
+return static function (ContainerConfigurator $containerConfigurator): void {
+    $parameters = $containerConfigurator->parameters();
+    $parameters->set(Option::ONLY, [
+        // this should be removed in the future, with all dead comments
+        SomeFixer::class => [__DIR__ . '/src/Controller'],
+    ]);
+};
+```
