Si, te adjunto mi código

<?php

require_once DIR . '/vendor/autoload.php';

use Bookstore\Core\Router;
use Bookstore\Core\Request;
use Bookstore\Utils\DependencyInjector;
use Bookstore\Core\Config;
use Monolog\Logger;
use Monolog\Handler\HandlerInterface;

$config = new Config();
$dbConfig = $config->get('db');
$db = new PDO(
'mysql:host=db;dbname=bookstore',
$dbConfig['user'],
$dbConfig['password']
);
$loader = new Twig_Loader_Filesystem(DIR . '/Controllers/views');
$view = new Twig_Environment($loader);
// $log = new Logger('bookstore');
// $logFile = $config->get('log');
// $log->pushHandler(new HandlerInterface($logFile, Logger::WARNING));
$di = new DependencyInjector();
$di->set('PDO', $db);
$di->set('Utils\Config', $config);
$di->set('Twig_Environment', $view);
// $di->set('Logger', $log);
$router = new Router($di);
$response = $router->route(new Request());
echo $response;

Composer:
