Build

Requires Go and Hugo Extended v0.163.3.

mise x go [email protected] -- ./setup.sh

The static site is written to public/. Pushes to main deploy to GitHub Pages via .github/workflows/.

Release content

Unreleased placeholders stay in the repository and _sidebar.md. Set draft: true in a page's YAML front matter to hide it from the published site and navigation. For a week's README.md, use cascade: {draft: true} to hide the entire week, including its lessons. Change true to false and rebuild to release it.

To preview drafts locally after running ./setup.sh:

hugo server --source .hugo-build/site --buildDrafts

Re-run ./setup.sh after editing the source files; the Hugo site is a generated copy.
