I'm trying to make a simple application with Slim, here is my code

$app = new \Slim\Slim(array( 'view' => new \Slim\Views\Twig() ));

    $view = $app->view();
    $view->parserOptions = array(
        'debug' => true,
    $view->parserExtensions = array(
        new \Slim\Views\TwigExtension()

    $view->parserExtensions = array(
        new Twig_Extension_Debug()


I'm new to Slim.

    Are you loading Slim manually or using Composer? we recommend you use Composer to get the best usage of Slim.
