+This subrepository holds experimental code and API types.
+
+**Warning**: Packages here are experimental and unreliable. Some may one day be promoted to the main repository, or they may be modified arbitrarily or even disappear altogether.
+
+In short, code in this subrepository is not subject to any compatibility or deprecation promise.
+
+For policy around graduation timeline, see [Cluster API Exp](https://github.com/kubernetes-sigs/cluster-api/tree/master/exp).
