It'd be nice to add typing to all the rest of the code examples in our extension docs, but that is a tedious job and not super necessary for this change.

It could be useful to add a section after this to explain some of the optional properties like allow_inline and supports_diffing.

While you're here can you add a trailing comma here.

And update this to renderContent() {.

And add a trailing comma here.

Since we already offer in house integrations with Slack and Asana, I wonder if we should replace them with different examples here.
Could even be nice to say "AI chat bots" here.

I think this looks great. Love the new introduction. I think the one thing I'm uncertain about is how much of the introduction lives on the front page. If I'm building an extension and want to find references, there's a lot to sort through to get to it. It might be better to keep the bulk of the steps for creating/activating/testing on a Getting Started page.

Two blank lines before reference definitions.

This isn't returning anything.

This is missing the version it was added in.

Extra blank line here.

Swap these.

This isn't returning anything.

This isn't returning anything.

This isn't returning anything.

"add new features"

These aren't consistent with trailing periods.

Probably don't want to capitalize "new" here.

Let's say "Python Virtual Environment" (so people know this is a thing and not, like, "we put it in Docker").

Instead of embedding the command, it might be nice to break this out into a separate code block.

This is missing a leading $ for the prompt styling.

I believe we normally use 4 space indentation inside definition lists.

The PEP won't mean much to anybody but us. If we reference it, we should probably just link it.

Let's call it the "Review Board devserver".

Ship It!

We always define references at the bottom of the section block, separated by two blank lines on either side.

Single backticks are an error. This should either be double or, more likely, a reference.

Ship It!
