How to optimize the uses controller in laravel route group?

Route::group(['as' => 'admin.documents', 'middleware' => 'permissions:volunteer', 'prefix' => 'admin/documents/'], function () {
    Route::get('', ['uses' => 'Admin\AdminDocumentsController@index',    'as' => '',         ]);
    Route::get('add', ['uses' => 'Admin\AdminDocumentsController@create',   'as' => '.create',  ]);
    Route::post('add', ['uses' => 
});

How can even optimize this code?
