Hi all,
I am making better progress on this walkthrough than I had anticipated. Right now it is at about 20% complete overall, and so on that basis I am aiming to complete it within another one or two weeks. I won't necessarily provide many further updates in this thread as I continue, but I do keep the walkthrough progress percentage up to date, which you can see on the Cocoon page's Walkthrough tab:
