    'middleware' => ['permission:manage-admins'], 
    'domain' => '{account}.myapp.com',
    'namespace' => 'Admin'
], function() {
    Route::get('/', 'AdminController@welcome');
    Route::get('/manage', [
        'middleware' => ['permission:manage-admins'], 
        'uses' => 'AdminController@manageAdmins'],
        'namespace' => 'User'
    );
