At first you need to include jQuery 1.4.0 or latest, jquery.simpleplaylist.js and simpleplaylist.css.
Then initialize the player after document loaded, e.g.:
$(document).ready(function() {
$('.playlist').playlist();
});
You can easly use CSS to style up this simple player by change of simpleplaylist.css or define it in your CSS files.
