This section is for those who will done the best documentation effort for their project.
So it’s not depending on the quality of your finished box/app project, but more on the way you document it.
“…AND howto for total Newbies” mean that, reading your doc, any newbees have to be able to build the thing you describe, even if they never hold an iron in their hand.
You can merge the doc related to your own project and the “total newbees HowTo” into the same document, or make two different document. I think the second choice will be more helpfull for the community.
