How to specify an entire directory to render docs from

[k3yss]

I want to specify an entire directory consisting of ~50 markdown files to render on the sidebar, what I want to the navigation bar to look like is

• Languages

  • Language1
  • Language2
  • ...
  • Language50

• Services

  • Service1
  • Service2
  • ...
  • Service50

  I tried to specify it this way but it doesn't seem to work

nav:
 - Home: index.md
 - Usage:
     - languages: reference/autogen/
     - services: reference/autogen/service/

Here is my entire mkdocs.yaml https://github.com/cachix/devenv/blob/main/mkdocs.yml
