 ## Running on Kubernetes via Helm
 
-wg-access-server ships a Helm chart to make it easy to get started on
-Kubernetes.
-
-Here's a quick start, but you can read more at the [Helm Chart Deployment Docs](https://freifunkMUC.github.io/wg-access-server/deployment/3-kubernetes/)
-
-```bash
-# deploy
-helm install my-release --repo https://freifunkMUC.github.io/wg-access-server wg-access-server
-
-# cleanup
-helm delete my-release
-```
+The Helm chart included in this repository has been removed due to lack of expertise on our side and nobody answering
+our call for aid.  
+If you are a Kubernetes/Helm user, please consider stepping up and taking over maintenance of the chart at
+https://github.com/freifunkMUC/wg-access-server-chart.
