Hi Eric,

I have (tried to) read this part of the manual. Not easy, particularly
the fact that the 2 sections on required and optional functions do not
mention de OO interface which appears later.

Right now, I am studying these backends:

nndiscourse - https://github.com/dickmao/nndiscourse.git
nnhackernews - https://github.com/dickmao/nnhackernews.git
gnus-twit - https://github.com/larsmagne/gnus-twit
nntwitter - https://github.com/dickmao/nntwitter.git

And I go back and forth between the manual and the source code of those.

I have also succeeded in generating buffers with contents from elfeed
functions, so I guess its just now a matter of time and struggle.

It is not yet clear to me if there would be an interest in deriving from
nnrss and just reimplementing the appropriate functions.

I have started a repository
(https://gitlab.com/garjola-emacs/nnelfeed/-/tree/master). There is
nothing useful there yet. Just some ideas, but I hope I will be able to
have some progress in the next months.

If anybody can give some pointers to other ressources I could have a
look at, I would be very grateful.

Thanks.
