-### 6 Steps to Add New Rector
-
-In case you need a transformation that you didn't find in Dynamic Rectors, you can create your own:
-
-1. Just extend `Rector\Rector\AbstractRector` class. It will prepare **2 methods**:
-
-```php
-public function isCandidate(Node $node): bool
-{
-}
-
-public function refactor(Node $node): ?Node
-{
-}
-```
-
-2. Put it under `namespace Rector\Contrib\<set>;` namespace
-
-```php
-<?php declare(strict_types=1);
-
-namespace Rector\Contrib\Symfony;
-
-use Rector\Rector\AbstractRector;
-
-final class MyRector extends AbstractRector
-{
-    // ...
-}
-```
-
-3. Add a Test Case
-
-4. Add to specific level, e.g. [`/src/config/level/symfony/symfony33.yml`](/src/config/level/symfony/symfony33.yml)
