I try to write docs like this. (Not markdown files, heaven forfend, and definitely not a random file in the root, of course, but these are quibbles.) A problem, though, is that many things lack an architecture; they were grown and are a mess, and the procedural knowledge can't be put to a document without just pointlessly recapitulating the code itself in what is possibly a more confusing form.
