Hi Paul,
Copy the Articulate publish(web) folder into Moodle directory. Open Moodle. Then, add a new label.
Embed code is:
<p align="center" valign="top"><iframe height="580" frameborder="0" width="750" scrolling="auto" src="http://your site adress/your Articulate folder name/engage.html" title="Presenter Test"></iframe></p>
I hope I could help you.
