Can a paper be a tutorial or textbook like?

Although I joined Codidact from the beginning, I was never truly active and lost track of the development of the system and this site in particular. 

I've read the help and the "paper" category looks interesting (it seems to address some of the suggestions I made in the very early brainstorming days of Codidact, e.g. a sort of "blog" space for authors).

Reading the help about papers it seems that the feature is meant for "paper-like" content, i.e. somewhat innovative content, but maybe I didn't get the whole picture.

Since the first bullet there is about "education", I wonder whether writing some tutorial/textbook-like material would be on-topic. Moreover I'd like to know if the level of the material need to be "high" (e.g. post-degree) or can also be lower (e.g. high-school or undergraduate). 

It goes without saying that it must be *quality* content, so I'm not asking about that. But my doubt is about the "innovation" thing. In fact, for example, I was considering writing a paper on what is a lumped parameter circuits and why/when it is useful. So no real innovation here (besides probably my writing style).

Is this acceptable on this site? When I joined Codidact I envisioned it also as a place where experts could put high-quality introductory material for newbies and students. Is the "paper" category such a place?
