Facebook integration

Has anyone seen this and understand how to implement it in a Revolution theme?

Facebook writes that “you can now incorporate Facebook Connect into your site in 3 easy steps.” The process is simple. First, you enter the name of your site and its URL. Then Facebook asks you to download and then upload a special file to your site’s main directory. And.. that’s about it. Once you’ve done that, Facebook will present you with its Playground — a list of code snippets you can embed on your site to round out the functionality, including Login buttons, profile photos, publishing items to News Feeds, and rendering photos of a user’s friends.[quote:1ycku4wh]http://www.techcrunch.com/2009/09/30/facebook-just-made-it-super-easy-to-put-facebook-connect-on-your-site/

Upload the xd_receiver.htm file to your website

In order for XXXXXX to communicate efficiently with our servers, you need to upload a small file to your site. This will ensure Facebook Connect works across all browsers and loads more quickly.

Can someone help me understand where I should upload and place the file to make this work properly within a Revolution theme?
