Augment README #4

Hi Folks,
Based on an announcement on the W3C DWBP mailing list, I checked out your codebase and added some docs provided on the list by Debattista, Jeremy <Jeremy.Debattista@iais-extern.fraunhofer.de>
I am still unsure how to use this code without digging in to it so there is no doubt that this README could be improved further.
Thanks
Lewis
