Adding ZergNet to my Blog

Hey everyone. I was wondering how I could integrate the ZergNet widget into my site. The Hueman theme is beautiful. I want it to populate below the comments section, above the footer.

Here’s the code that the website generated:

<div id="zergnet-widget-18732" style="text-align:center;"></div>

<script language="javascript" type="text/javascript">
	(function() {
		var zergnet = document.createElement('script');
		zergnet.type = 'text/javascript'; zergnet.async = true;
		zergnet.src = 'http://www.zergnet.com/zerg.js?id=18732';
		var znscr = document.getElementsByTagName('script')[0];
		znscr.parentNode.insertBefore(zergnet, znscr);
	})();
</script>

Not too sure where I should put it.
