@dharmabumstead since this PR removes the old intro_network page, I'd like to set a redirect from there to the new network page, so external links remain workable. I've heard you're doing a bunch of redirects as part of your refactoring work - can you add this one to the list? I'm happy to help when you get to that stage.

Just a minor thing

Current docs have inconsistent header styling (it has probably accumulated through the years). I'd prefer to discuss this, come up with a consistent notation, and submit one PR that makes all the docs use the same notation.

Created #35520 to address this.

[gundalow]

Agreed. Ignore this comment and we can address this in the bulk fix up PR.

As long as Shippable RST check passes (which it is) I'm happy.

This is a great start! Nicely done, @acozine!
