Xbee with shield from iteadStudio and Romeo V2.0 from DFRobot?

Has anyone tried to run XBee using the iteadStudio XBee shield V1.1? I can’t find a lot of documentation on this shield. If there’s a tutorial out there floating around…
Also, the Romeo V.20 microcontroller from DFRobot has a built in XBee shield. So it’s just supposed to be plug, code, and play. I can’t seem to find anything detailing programming to communicate through the XBee module.

I’m trying to use any one controller to read data standalone, send the data values through the XBee module, receive the data with the other controller plugged into my computer via USB, and display the data on the Serial Monitor in Arduino environment. Any tips?

Not even a link to the shield?
