-This checker imports single name classes like `\Twig_Extension` or `\SplFileInfo` by default. But if you need, you can **configure it**:
-
-```yaml
-# ecs.yml
-services:
-    Symplify\CodingStandard\Fixer\Import\ImportNamespacedNameFixer:
-        allow_single_names: true # false by default
-```
-
-You can also configure to check `/** @var Namespaced\DocBlocks */` as well:
-
-```yaml
-# ecs.yml
-services:
-    Symplify\CodingStandard\Fixer\Import\ImportNamespacedNameFixer:
-        include_doc_blocks: true # false by default
-```
-
-And what about duplicate class name? They are uniquized by vendor name:
-
-```php
-<?php declare(strict_types=1);
-
-namespace SomeNamespace;
-
-use Nette\Utils\Finder as NetteFinder;
-use Symfony\Finder\Finder;
-
-class SomeClass
-{
-    public function create(NetteFinder $someClass)
-    {
-        return new Finder;
-    }
-}
