A while back I started working on a Vala GTK+ tutorial in the vein of the classic GTK+ tutorial for C.
You can find it on https://github.com/abenga/valagtktutorial I managed to work on the first 7 chapters, you can find them in the */content/ folder.* I've held off on posting here about the effort untilI had a reasonable amount of content, but I'm thinking I'll probably ask for help as I've been really busy recently. I recently started working on porting it to Docbook XML, and I hope to be done in a couple of months or so. Regards, Horace.
