Thank you Dave for your words!
As the most time, you hit the nail. As you write I think about a book more like a workshop manual or technical.
So in the moment it looks my wish wouldn't go true.
About youtube: one of my friends like this manuals. But it isn't my cup ot tea. With oily fingers and the tablet looking for the kingpins?
And a lot of videos the guys looks out of knowledge.
