The site that got me into programming as a teenager was called "FromZero" and explained how to write programs in C for non-developpers. From installing the IDE, to how to open the console, it carefully explained each step, sometimes saying "don't worry about Snarfus, we'll get into that later". It was amazing, and I owe this website my career.
That being said, I agree writing doc is time consuming and it might not be your priority, in this case partial docs is better than no docs at all. But if your target is beginner developpers, imo you should consider them as non-developpers, as you correctly descibed them.
Site du Zéro mentioned!
I always assumed it meant "a website for 'zeros'" as in "complete noobs"
I owe so much to that website. I first had access to a computer at 13, some nights of the week and only some of those nights did I also have internet access. Somehow I still discovered le Site du Zéro at that time. While I barely touched a computer the year before, I still was able to go through the whole C++ class and learned most of the basic things and reflexes I've ever needed to work in software development. That makes it really hard to listen to people who dismiss C++ because it's "not beginner friendly".
They used to have "users" who are more advanced in a class review the work of people who are behind them, and that's how you got credits to get your own homework reviewed (based on what I remember). I still daydream about building something like that, not just to learn programming, but for everything.
Now openclasssrooms is really weird, no idea what's going on on there. Their landing page is like a synthesis of every corporate website ever made. But I found an archive of the content of the old website here: http://sdz.tdct.org/
SDZ should have been Heaven for me, but even as a teenager, I just couldn't get past the omnipresent enthousiasm and the smileys at the end of each sentence :)

Guess I've always been grumpy.
Oh and yeah it's probably been enshittified nowadays, everything has. Wouldn't surprise me if they partnered with Ecole 42 to inundate the job market with programmers without degrees and drive the salaries down even more.
