In nix shell,
just runSlugs must in the form of either of the following:
/foo: A single component slug for all docs by default/<module>/foo: Documentation for page "foo" under flake-parts module named "".
Unfortunately, Docusaurus is not great with cross-linking, so you must always link to pages using slugs (see section above) rather than file paths. If a link is broken, then the Docusaurus build will fail.
When editing the docs of your flake-parts modules, if there is a git submodule reference to them, you can do those edits in that submodule checkout. The local server will pickup those changes.
Individual module's docs are stored as git submodules. Run just update to update them all.
