Arduino Fio / XBee tutorial

Does anyone have a link to a solid Arduino Fio & XBee setup?

I have two XBee Pro's and the Fio and would like to use it just like any regular Arduino, just having the serial communication going over the XBee's. All tutorials (such as on the Fio page) which I have found implicitly assume, that you know how to use an XBee.

Was just wondering whether someone here knows of a nice step-by-step writeup of getting this to work using windows 7
