+### CI / GitHub Actions
+
+Two workflows in `.github/workflows/`:
+
+| Workflow | Trigger | Purpose |
+|----------|---------|---------|
+| `ci.yml` | Push to `main`, PRs | Tests + mypy on Python 3.11 and 3.12 |
+| `release.yml` | Push of `v*.*.*` tag | Tests → build → publish to GitHub Releases |
+
+**To publish a release**: commit bumped version → `git tag vX.Y.Z` → `git push --tags`.  
+CI runs tests, builds wheel + tarball, creates a GitHub Release with packages attached.
