Generated code in phalcon developer tools is different than tutorial

First, sorry for the title because I confuse how to determine the right title. I'm new in phalcon. I install it and succeed (version 1.3.4). I also install phalcon developer tools. When I run new project using phalcon project tutorial (tutorial is name of the project), it give the right folder. When I open public/index.php the code structure is like this :

<?php

error_reporting(E_ALL);

try {

    /**
     * Read the configuration
     */
    $config = include __DIR__ . "/../app/config/config.php";

    /**
     * Read auto-loader
     */
    include __DIR__ . "/../app/config/loader.php";

    /**
     * Read services
     */
    include __DIR__ . "/../app/config/services.php";

    /**
     * Handle the request
     */
    $application = new \Phalcon\Mvc\Application($di);

    echo $application->handle()->getContent();

} catch (\Exception $e) {
    echo $e->getMessage();
}

that's different with another phalcon tutorial. Can someone explain this differences? Which one I should follow to try?

Thank you
