Hi Emma,
I'm glad you liked it :) and, yes, the content of this tutorial will become part of the documentation in the near future, I have taken the job of updating the documentation for the next release ( job #1 described here: http://docs.google.com/Doc?id=ddjwq8c5_9g7jgtbcm ) I'm starting to plan how I will be approaching this job and will post my work plan to get some feedback before starting, but definitely the content of the tutorial will find its way there.
