+# Routes
+
+By default, Lean will pass the `Request`, `Response` and route parameters to your routes. Alternatively, you can access the route parameters through the `getAttribute` method of the request.
+
+```php
+$app->get('/books/{id}', function (Request $request, Response $response, array $args) {
+    $id = $args['id'];
+    // Or
+    $id = $request->getAttribute('id');
+});
+```
+

+
+# Method Injection
+
+Method injection allows you to define dependencies on a method level, rather than in the constructor (similar to the Laravel framework). If you want to enable method injection you can enable setting the `methodInjection` setting:
+
+```php
+$app->getContainer()->get(\Slim\Settings::class)->set('methodInjection', true);
+
+$app->get('/books/{id}', function (Request $request, string $id) {
+    // ...
+});
+```
+
+Route attributes are only available as method parameters and will not be accessible through the `getAttribute` method on the request object.

 ## Error Handlers
 
 By default, Lean uses Slim's error handlers. There are different ways to implement an error handler for Slim, read more about them [here](https://www.slimframework.com/docs/v3/handlers/error.html).
