The steps are clear enough I could definitely build this coop. The only thing missing was a bit of explanation on why you decided to go with this coop and some other supportive information for members who might not already know about this coop style.
I thinm you should do a seperate article for the coop automation. There's not a lot of info on BYC about using rasberry pi's (or other simple electronics) and I think that would be very helpful for a lot of people. Nice article and sweet coop!
