Needing help installing Phalcon

Hello,

I'm getting this error on my website Fatal error: Class 'Phalcon\Loader' not found in /home3/website/public_html/public/index.php on line 19

Here is what my index.php says:

use Phalcon\Loader;
use Phalcon\Mvc\View;
use Phalcon\Mvc\Application;
use Phalcon\Di\FactoryDefault;
use Phalcon\Mvc\Url as UrlProvider;
use Phalcon\Db\Adapter\Pdo\Mysql as DbAdapter;
use Phalcon\Flash\Direct as FlashDirect;
use Phalcon\Flash\Session as FlashSession;
use Phalcon\Mvc\Dispatcher;
use Phalcon\Events\Manager as EventsManager;
use Phalcon\Mvc\Dispatcher as MvcDispatcher;
use Phalcon\Events\Event;
use Phalcon\Mvc\Dispatcher\Exception as DispatchException;
use Phalcon\Session\Adapter\Database as Database;
use Phalcon\Mvc\View\Engine\Volt;
use Phalcon\Mvc\Router;

$loader = new Loader();

$loader->registerNamespaces([
    'Phalcon' => "../Library/Phalcon/",
]);

When I type in Loader into my webfiles, it comes up in two places. Phalcon/Config/Loader.php and Phalcon/Mvc/Model/Eagerloading

Is there something I need to put in the Phalcon folder that's not already there?
