+## Versioning policy ##
+`ariadne-codegen` follows a custom versioning scheme where the minor version increases for breaking changes, while the patch version increments for bug fixes, enhancements, and other non-breaking updates.
+
+Since `ariadne-codegen` has not yet reached a stable API, this approach is in place until version 1.0.0. Once the API stabilizes, the project will adopt [Semantic Versioning](https://semver.org/)..
