Twitter feed with scrolling

/* Twitter Feed */

jQuery(function ($) {
    var $twitterList = $('.home-twitter > .inner');

    if (!$twitterList.length) {
        return;
    }

    // Twitter list has been filled with data
    // Start spinning
    function startRotating() {
        $twitterList.jCarouselLite({
            vertical: true,
            pause: true,
            visible: 2,
            auto: 800,
            speed: 500
        });
    }

    // Get data from Twitter
    function initialize() {
        $twitterList.
            bind('full', startRotating).
            tweet({
                username: "taylorswift13",
                count: 6,
                loading_text: "Loading Twitter feed...",
                template: "{text}"
            });
    }

    initialize();
});

I have added the file to my script folder and added <script src="script/twitter.js" type="text/javascript" ></script> to my head but what do I need to add to the HTML body to call/activate the code form the JavaScript file ?
Cheers
