The installation process using the Helm charts is as follows:

1) `base` chart creates cluster-wide CRDs, cluster bindings and cluster resources. It is possible to change the namespace from `istio-system` but it is not recommended.

```console
helm install istio-base -n istio-system manifests/charts/base --set profile=openshift
```
