There are several ways to get Overlay feeds to incorporate on your site.

The best way is to get the OZ gadget and just drop it in your site (no programming needed).
The OZ Gadget requires ASP.NET.

There are also 2 RSS feeds. One for current overlay tournaments (starting within 5 minutes) and another for a weekly summary (top in terms of overlay %).
