+[org-roam](https://www.orgroam.com/) is a plain-text personal knowledge management system for [emacs](https://en.wikipedia.org/wiki/Emacs). [ox-hugo](https://github.com/kaushalmodi/ox-hugo) is org exporter backend that exports `org-mode` files to [Hugo](https://gohugo.io/) compatible Markdown.
 
 Because the Markdown generated by ox-hugo is not pure Markdown but Hugo specific, we need to transform it to fit into Quartz. This is done by `Plugin.OxHugoFlavouredMarkdown`. Even though this [[making plugins|plugin]] was written with `ox-hugo` in mind, it should work for any Hugo specific Markdown.
