Which reading order would you suggest for Asimov’s Foundation Series newbie?

I would start with the Foundation trilogy first (Foundation, Foundation and Empire, Second Foundation). Foundation for me was a perfect book. I don't remember if I finished the robot series though, and the books looking at Wiki, have a ton of content continuing on the original universe. I mean if I started at episode I of Star Wars I never would have made it to episode IV. One of my favorite things about Asimov in general is that he is overall optimistic about the future, some of his short stories are really good too, a time-traveling Shakespeare one stuck out for me.

Definitely in the order that they were written.

Afterthought sequels and prequels never fit properly into the original sequences.
