-Routing Component
-=================
-
-The Routing component maps an HTTP request to a set of configuration variables.
-
-Getting Started
----------------
-
-```
-$ composer require symfony/routing
-```
-
-```php
-use App\Controller\BlogController;
-use Symfony\Component\Routing\Generator\UrlGenerator;
-use Symfony\Component\Routing\Matcher\UrlMatcher;
-use Symfony\Component\Routing\RequestContext;
-use Symfony\Component\Routing\Route;
-use Symfony\Component\Routing\RouteCollection;
-
-$route = new Route('/blog/{slug}', ['_controller' => BlogController::class]);
-$routes = new RouteCollection();
-$routes->add('blog_show', $route);
-
-$context = new RequestContext();
-
-// Routing can match routes with incoming requests
-$matcher = new UrlMatcher($routes, $context);
-$parameters = $matcher->match('/blog/lorem-ipsum');
-// $parameters = [
-//     '_controller' => 'App\Controller\BlogController',
-//     'slug' => 'lorem-ipsum',
-//     '_route' => 'blog_show'
-// ]
-
-// Routing can also generate URLs for a given route
-$generator = new UrlGenerator($routes, $context);
-$url = $generator->generate('blog_show', [
-    'slug' => 'my-blog-post',
-]);
-// $url = '/blog/my-blog-post'
-```
