 <!-- Describe what this PR changes and why. -->
 
-## Type of change
+## PR title (important)
 
-- [ ] Bug fix
-- [ ] New feature
-- [ ] Breaking change
-- [ ] Documentation update
-- [ ] CI / tooling
+Use a **conventional commit** title — it becomes the release version on merge:
+
+| Title prefix | Release bump | Example |
+|--------------|--------------|---------|
+| `fix:` | patch (1.5.5 → 1.5.6) | `fix: correct Content-Length parsing` |
+| `feat:` | minor (1.5.5 → 1.6.0) | `feat: add rate limiter middleware` |
+| `feat!:` or `BREAKING CHANGE:` in body | major (1.5.5 → 2.0.0) | `feat!: rename cHTTPX_Parse signature` |
+| `chore:`, `ci:`, `docs:` | no release tag | `chore: update workflows` |
+
+> Use **Squash merge** so the PR title becomes the commit on `main`.
