# How To Configure Rules
Rector rules that implement `Rector\Core\Contract\Rector\ConfigurableRectorInterface` can be configured.
Typical example is `Rector\Renaming\Rector\Name\RenameClassRector`:
```php
use Rector\Renaming\Rector\Name\RenameClassRector;
use Rector\Config\RectorConfig;
return static function (RectorConfig $rectorConfig): void {
$rectorConfig->ruleWithConfiguration(RenameClassRector::class, [
'App\SomeOldClass' => 'App\SomeNewClass',
]);
};
```
