How to do the following

```php
$router->get('/', 'index.php');
$router->get('/about', 'about.php');
$router->get('/contact', 'contact.php');

$router->get('/notes', 'notes/index.php')->only('auth');
$router->get('/note', 'notes/show.php');
$router->delete('/note', 'notes/destroy.php');

```


The issue shows PHP route definitions and a screenshot but does not name a file, test, or specific behavior to change. Clarify the intended routing outcome and identify the relevant entry point before deciding what implementation and verification would constitute done.
