[Plugin: WordPress Popular Posts] Adding additional code to the shortcut

this might be a stupid question, but how do I add the additional code to the shortcut this is what I have, not sure where to add stuff like excerpts for the post, thumbnails etc…

<?php if (function_exists(‘wpp_get_mostpopular’)) wpp_get_mostpopular(“range=weekly&order_by=views”); ?>

any help would be great!!
