IMHO the Elisp reference is not the place to teach how file systems
handle content. As Stefan noted the Emacs workflow is not all that
different from what you could do with most popular APIs (POSIX, WIN32,
etc).

I think that the info nodes "Buffer basics" and the linked "Visiting
files" give a good hint about how to solve your task, supposing that you
know that on most operative systems it is not possible to directly
insert content on a file and you need to fake the operation.
