laravel-shareable-models: route is not working

There are some problems with documentation.

1. the entry to be put in the routes file has a typo:

Route::get('shared/{shareable_link}', ['middleware' => 'shared', function (ShareableLink $link) {
    return $link->shareable;
});

A closing bracket ] is missing.

1. the route doesn’t work anyway. To be honest I have no idea why. I tried to link the route to middleware using an alternative syntax

Route::get('shared/{shareable_link}', function (Sassnowski\LaravelShareableModel\Shareable\ShareableLink $link) {
    return 'test OK';
})->middleware('shared');

But to no result.

Maybe you could run the package on a clean new instance of Laravel 5.5?

1. In docs here https://ksassnowski.gitbooks.io/shareable-models/content/getting-started.html it would be nicer if you mention that the user should declare the class in the header of the controller file: use Sassnowski\LaravelShareableModel\Shareable\ShareableLink;

The package should be great, anyway! Thank you.
