Danny, the IndieWeb page for Hugo has lots of resources for this (and other fun things). You should also check out the static site generator page and links for other examples/documentation which can be roughly similar.

Good luck!

My IndieWeb setup is continuing to evolve. I just added support for syndication (this post should appear on IndieNews) and JSON-posting to my Hugo backend and theme.
Congratulations! I’m sure you’ve found lots of documentation, but keep in mind that micro.blog is built on Hugo. If it helps I noticed that Steve Layton wrote a piece the other day about adding Webmention to micro.blog/Hugo with lots of code and details. It looks like you may have some of that already, but seeing the previously worn paths and knowing where to turn can help a lot!
