Awesome work @bholmesdev! Still need to get to the last part of this (“Generating pages…” and below) but er… this should be enough feedback to start off with 😅

Looks good! Left a couple of small fixes. If we have time, one thing I’d do: reorg the “Rendering page content from entries” so that the intro paragraph covers render() in general (e.g. including headings) and the first subhead render() is focused on <Content />. At the moment we kind of have two sections describing <Content /> to introduce render() and then the other return types. A quick snippet that shows something like this could be handy:

const { Content, headings, injectedFrontmatter } = entry.render();

Running out the door but I can take a close look at doing that if it would be helpful.

I hereby declare myself… CONTENT! 🥳
