With the Git repository not quite set up yet (thanks Keith or all the work!), I have held off on updating the checkout spreadsheet since I think we will ultimately use a different method. I have just finished my first pass at AOO41GS5 and I will move on to 6.
It would be good to have the checkout document separate from the branch being edited so you don't have to do a pull request of all of the edits just to notify that you have moved on to other chapters. Could there be a global check out document in Main? Francis
