+## Support Matrix
+
+Currently, there are several major versions under maintenance, each tailored to different Kubernetes version ranges due to the use of varying steve and client-go versions.
+
+| Major | Target Rancher Branch | K8s version range |
+| ----- | --------------------- | ----------------- |
+| v0.4  | v2.8.x                | >= 1.25 <= 1.28   |
+| v0.5  | v2.9.x                | >= 1.27 <= 1.30   |
+
+Please use the proper kube-explorer version for your k8s setup.
