Hmm. I know I had a couple vague thoughts in my head for what an "Overview" page would contain, but I'm not sure what those were atm. I think I was picturing something that was more of a cross between the "RTKQ Tutorial" page and a "why should we do this data fetching stuff via RTKQ anyway?" writeup.

I don't think this is quite what I was picturing, but it's good material anyway.

I'd actually suggest we just consolidate the RTKQ-specific content here into the existing "Getting Started" page as an additional section - no need to repeat all the install info.

That's a good idea, I'll change it up like that

Looks better! Not sure "Installation" is the right word for that header, since we're not actually installing anything. Can't come up with a good alternate header phrase atm - maybe just drop that "Installation" header entirely and have that code block be directly after the preceding couple of paragraphs?

Ah, I had the same reservations as you trying to come up with a more accurate header, but didn't even consider "no header" as an option. I was thinking it was roughly accurate in the sense that it is "here is how to install: it's already installed". But forgoing the header is definitely better

LGTM!

I do plan on doing a typos/editing pass over the docs before release, so I'm not doing much review on those atm.
