Thanks for such a detailed walkthrough! I watched the video version at 2x speed and find it still quite easy to follow. Being able to see the screen is useful, especially around filling out metadata for Post Kinds. I think this also serves well as a WordPress 101 for newbies like me. I popped out of the video a few times just to try what you’re showing.
This reply is a test run of webmention. Hopefully it works! 🙂
