[Plugin: WP Facebook Timeline (MF Timeline)] How to call the code

Nice plugin, I like it. But how to call the plugin through the short code [mf_timeline] or call <?php echo $mf_timeline->get_timeline(); ?> in templates?

Is there a document to tell how to do it? Anyone teach me? Thank you very much.
