        $container = $this->getContainer();
        $container->registerService('Config', function($c) {

            return $c->query('ServerContainer')->getConfig();
        });

        $container->registerService('RootFolder', function($c) {

            return $c->query('ServerContainer')->getRootFolder();    // <<<<<<<=====
        });
        $container->registerService('UserManager', function($c) {
            return $c->query('ServerContainer')->getUserManager();
        });
    }
