# Istio operator code overview

## Introduction

This document covers primarily the code, with some background on how the design maps to it.
See the

for a more complete design description. The operator code is divided roughly into five areas:

1. [IstioOperatorSpec API](#istiooperatorspec-api) and related infrastructure, which is expressed as a
