## Introduction

WARNING: when installing over an existing deployment, the two deployments will be merged together by Helm, which may lead to unexpected results.

#### Legacy Gateway Helm charts

Istio historically offered two different charts - `manifests/charts/gateways/istio-ingress` and `manifests/charts/gateways/istio-egress`.
