This document is an overview of how the operator works from a user perspective. For more details about the design and
architecture and a code overview, see [ARCHITECTURE.md](../architecture/environments/operator.md).

## Introduction

The operator uses the [IstioOperator API](https://github.com/istio/api/blob/master/operator/v1alpha1/operator.proto), which has
