This provides maximum flexibility with minimal API surface overhead.

## Making changes

## Step 1. Make changes in charts and values.yaml in `manifests` directory

Be sure to provide sufficient documentation and example usage in values.yaml.
If the chart has a `values.schema.json`, that should be updated as well.

## Step 2. Update the istioctl/Operator values

### Install Istio CRDs

This is the first step of the installation. Please do not remove or edit any CRD - config currently requires
all CRDs to be present. On each upgrade it is recommended to reapply the file, to make sure
you get all CRDs.  CRDs are separated by release and by component type in the CRD directory.

Istio has strong integration with certmanager.  Some operators may want to keep their current certmanager

# the needed environment variables.
