Laravel 5.5 Resource Controller and Dependecy Injection

I am working on a Laravel 5.5 application. When I use php artisan make:model SomeModel -mr it creates the model, migration and resource controller.

I've been noticed that some methods have by default only one parameter: the model:

public function show(SomeModel $someModel)
{
    ...
}

If you look into the $someModel variable it has an empty SomeModel object.

I was reading on Laravel Documentation that it looks like the Containers or Facades but I am not sure how to use this. Do you?
