How do I use this?

Want to use this on html but there is no documentation on even how to use this.

<script>
new FPSMeter(document.querySelector('yourelement#yourid.oryourclass'))
</script>

Do I need to direct it to the js files to make it work? I made a index html fine in the root of the fpsmeter folder and selected the id of a iframe but it didn't works so I am obviously doing it wrong.
