### Installing with Helm
The Istio CNI and Istio discovery chart use different values that require you set the following, either in an overrides values file or at your command prompt when installing the `istiod` chart, to manage network annotations when chaining CNI plugins:
Following the [Install with Helm](/docs/setup/install/helm/#installation-steps) installation steps, there are some additional Helm values that are required to be set. You can
set these either through an override values file or via the command line when installing the `istiod` chart. These are:
* `values.istio_cni.enabled` should be set to the same value as `values.cni.enabled`.
* `values.istio_cni.chained` should be set to the same value as `values.cni.chained`.
For example:
{{< text bash >}}
$ helm install istiod istio/istiod -n istio-system --set values.istio_cni.enabled=true --wait
$ helm install istiod istio/istiod -n istio-system --set istio_cni.enabled=true --wait
{{< /text >}}
