Just finished it.
I don’t think I would have put it in the easy category.
Obviously, once you get it done, the process looks fairly straight forward, but finding the way and the tools…
I did learn from it, tho, so thanking the creators is in order. And also @Ketil and @polarbearer of course.
Hints:
User: You have most likely already done something very similar in other boxed (I can think of two at least).
Root: As mentioned before, the hound will find the way for you 
Happy to assist if anyone needs a push.
