Onboarding documentation can make a huge difference. I had a discussion post about this back in 2018. Lots of good answers in there.
What is this "documentation" you speak of?
I completely agree - one of the reasons I've been writing articles like this and this on DEV is that at Alcumus we need some core (and perhaps less usual) principles to be understood before looking at the real code. I felt I might as well document those things as principles and then share them more widely.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
