-## Helm Chart
-

-
-Once Helm has been set up correctly, add the repo as follows:
-```shell
-helm repo add csp33 https://csp33.github.io/cert-manager-duckdns-webhook
-```
-
-If you had already added this repo earlier, run `helm repo update` to retrieve
-the latest versions of the packages.  You can then run `helm search repo
-csp33` to see the charts.
-
-To install the <chart-name> chart:
-```shell
-helm install cert-manager-duckdns-webhook csp33/cert-manager-duckdns-webhook
-```
-To uninstall the chart:
-```shell
-helm uninstall cert-manager-duckdns-webhook
-```
