This is the basic HTML structure required:

<div id="my-carousel">
    <ul>
        <li>
            <!-- item 1 content -->
        </li>
        <li>
            <!-- item 2 content -->
        </li>
        <li>
            <!-- item 3 content -->
        </li>
        <li>
            <!-- item 4 content -->
        </li>
        <li>
            <!-- item 5 content etc. -->
        </li>
    </ul>
</div>

Here's some CSS to get you going (I've flagged which declarations are required):

#my-carousel ul {
    position:absolute; /* required */
    overflow:hidden; /* required */
    margin:0;
    padding:0;
    list-style:none;
}
 
#my-carousel ul li {
    float:left; /* required */
    width:100px;
    height:200px;
    margin:0 10px 0 0;
}
 
#my-carousel .mask {
    position:relative; /* required */
    overflow:hidden; /* required */
    width:540px; /* required */
}
 
#my-carousel .pagination-links {
    list-style:none;
    margin:0;
    padding:0;
}
 
#my-carousel .pagination-links li {
    display:inline;
}
 
#my-carousel .pagination-links li.current {
    background:grey;
}
 
#my-carousel .disabled {
    color:grey;
}

And here's the JavaScript:

$(document).ready(function() {
    $('#my-carousel').carousel();
});

You can pass in any number of options from the following defaults:

{
    itemsPerPage: 1, // number of items to show on each page
    itemsPerTransition: 1, // number of items moved with each transition
    noOfRows: 1, // number of rows (see demo)
    nextPrevLinks: true, // whether next and prev links will be included
    pagination: true, // whether pagination links will be included
    speed: 'normal', // animation speed
    easing: 'swing' // supports the jQuery easing plugin
}

The plugin supports multiple carousels on a single page and maintains jQuery's chainability so usage should feel pretty familiar but if you do become stuck see the demo or leave me a message.
