+## Release Methodology
+
+We try to make a release whenever have something worth sharing to users (bug fix, minor or large
+feature, etc.). TorchJD follows [semantic versioning](https://semver.org/). Since the library is
+still in beta (`0.x.y`), we sometimes make interface changes in minor versions. We prioritize the
+long-term quality of the library, which occasionally means introducing breaking changes. Whenever a
+release contains breaking changes, the [changelog](CHANGELOG.md) and the GitHub release notes always
+include clear instructions on how to migrate.
