+To make this available for our Helm users, please make sure you update the
+image version in
+
+- `charts/kured/values.yaml` (`tag`) and
+- `charts/kured/Chart.yaml` (`appVersion`) as well.
+
+Finally bump the `version` in `charts/kured/Chart.yaml` and you should be
+all set.
+
 Now you can head to the Github UI, use the version number as tag and upload the
 `kured-<release>-dockerhub.yaml` file.
