Documentation Publishing

The ZPLC documentation is built using Docusaurus and automatically deployed to GitHub Pages via GitHub Actions.

The Deployment Pipeline​

The pipeline is defined in .github/workflows/docs-deploy.yml and runs as Deploy Docusaurus to GitHub Pages. It handles both pull requests and pushes to the main branch.

Pull Requests (Validation)​

When a PR is opened that modifies the docs/ directory:

  1. The CI pipeline installs dependencies.
  2. It runs bun run validate:v1.5-docs and then bun run build.
  3. Crucially, Docusaurus is configured with onBrokenLinks: 'throw'. If your PR introduces a broken internal link, a missing markdown import, or invalid frontmatter, the build will fail, blocking the merge.

Merges to Main (Deployment)​

When changes are pushed to main (or master):

  1. The CI pipeline performs the build validation step.
  2. It uploads the docs/build directory as an artifact.
  3. A subsequent job deploys that artifact directly to the github-pages environment.

Release Procedure​

To publish new documentation:

  1. Make your changes in a feature branch.
  2. Run cd docs && bun run validate:v1.5-docs locally to verify manifest parity and generated references.
  3. Open a Pull Request.
  4. Wait for the Build Documentation job in Deploy Docusaurus to GitHub Pages to pass.
  5. Merge the PR or push the approved change to main. GitHub Actions will upload docs/build and deploy it to GitHub Pages automatically.

Versioning a Release​

When the ZPLC project hits a release milestone (for example, v1.5.0), you should take a snapshot of the documentation.

  1. Create a branch for the release.
  2. Run cd docs && bun run docusaurus docs:version 1.5.0.
  3. Commit the new versions.json and the versioned_docs/ folder.
  4. Merge the PR.

Rollback Procedure​

If a bad deployment reaches production:

  1. Identify the commit hash of the last known good documentation state on the main branch.
  2. Use git revert <bad-commit-hash> to undo the changes.
  3. Push the revert directly to main (or via a rapid PR). The CI pipeline will rebuild and deploy the previous working state.
