Reading this I realized that the only emacs internal documentation I read in so many years are the help files of C-h w (where is a function, I'll type its name next), C-h k (what a keybinding does, I'll press it) and maybe the description of the current modes (is it C-h m ?) Everything else is a query to a web search engine. That has the advantage of people explaining things and finding solutions instead of only a reference.
