There is a note just under this section that states that the `Illuminate\Routing\Controllers\HasMiddleware` contract cannot be used in conjunction with ` App\Http\Controllers\Controller` yet the example itself has the class extending `Controller`.

I can confirm that if the class extends `Controller` you will get an error:

"Cannot make non static method Illuminate\Routing\Controller::middleware() static in class App\Http\Controllers\ArticleController"

This correction is applicable to documentation for Laravel 11.x and up.
