+## Versioning
+
+Theme follows simple incremental versioning. e.g. `v1`, `v2` and so on. There might be breaking changes between versions.
+
+If you want lower maintenance use one of released versions. If you want to live on the edge of changes you can use `master` branch and update your website when needed.
