I hope this helps. Feel free to look at the source for my website (http://zzamboni.org/) for inspiration: https://github.com/zzamboni/zzamboni.org. I only recently started migration to org-mode/ox-hugo. You can find all my old posts at https://github.com/zzamboni/zzamboni.org/tree/master/content, and the newer ones, generated from an org-mode file, at https://github.com/zzamboni/zzamboni.org/blob/master/content-org/zzamboni.org.
