At a certain point, it's more efficient to read the primary source of educational material, which is the documentation of whatever project/language you're working with. With some exceptions for complicated domains, it's usually much more efficient to read the docs rather than some tutorial that has probably drifted out of date. If you're interested in how other projects manage things, just read their code on github.
