Zend Framework - Index.php

So...I'm doing my first Zend Framework project and the index.PHP code is as such

"<?php

// Define path to application directory
set_include_path(implode(PATH_SEPARATOR, array(
    || define('APPLICATION_PATH', realpath(dirname(__FILE__) . '/../application'));

// Define application environment
defined('APPLICATION_ENV')
    || define('APPLICATION_ENV', (getenv('APPLICATION_ENV') ? getenv('APPLICATION_ENV') : 'production'));

// Ensure library/ is on include_path
set_include_path(implode(PATH_SEPARATOR, array(
    realpath(APPLICATION_PATH . '/../library'),
    get_include_path(),
)));

/** Zend_Application */
require_once 'Zend/Application.php';

// Create application, bootstrap, and run
$application = new Zend_Application(
    APPLICATION_ENV,
    APPLICATION_PATH . '/configs/application.ini'
);
$application->bootstrap()
            ->run();"

When I build the project it comes up on the index.phtml page....

Where in that "index.php" code does it direct to the "/application/views/scripts/index/index.phtml"?

I'm trying to understand how that gets routed and can't figure it out.

Thanks
