Ask HN: Best source to learn home renovations

I'm trying to find the best source that explains clearly how to do specific tasks such as replacing a toilet, bathtub, tile work, electric gate, garbage disposal, countertop, septic considerations, when to hire out because the tools are unique and not worth it, etc.

I know this is a generic question to an extent, and that the level of knowledge of the person learning will dictate the source. However, that's why I reached out to this community. I feel pretty good doing most work, including wood work, with a clear set of schematics or direction. Unfortunately, most sources I find are a surface-level single page description and, for lack of a better term, click-baity. I want the engineer's resource for home everything.

And if one doesn't exist - that may be my next web-project.
