+# Versioning And Release
+
+## Versioning policy
+
+- Use Semantic Versioning: `MAJOR.MINOR.PATCH`.
+- Git tags must follow: `vMAJOR.MINOR.PATCH` (example: `v0.2.0`).
+
+## Changelog policy
+
+- Every release must have a dedicated section in `CHANGELOG.md`.
+- Keep the following section structure:
+  - `Added`
+  - `Changed`
+  - `Fixed`
+- Move relevant entries from `[Unreleased]` into the new release section.
+
+## Release flow
+
+1. Make sure `develop` is green in CI.
+1. Run manual smoke checks from `docs/release_smoke_checklist.md`.
+1. Update `CHANGELOG.md` with a new version header and date.
+1. Create and push a tag: `git tag vX.Y.Z && git push origin vX.Y.Z`.
+1. GitHub Actions `release.yml` publishes artifacts and release notes.
+
+## Release notes source
+
+- Release notes are generated from the section matching the pushed tag in `CHANGELOG.md`.
+- If no matching section is found, the workflow falls back to auto-generated notes.
