Ideally your deployments are code. And tutorials are part of your website 'code', or integrated into your project (and thus 'code'). General graphs of the architecture would be docs in your code repo (and thus 'code' too). I'll admit tho that it's pretty sensible to just not consider some of those as 'code' and thus conclude that documentation outside of the code is important too.

But the original commenter is also probably right that 'second hand' documentation is probably the least accurate.
