 **This application was forked from [microservices-demo](https://github.com/GoogleCloudPlatform/microservices-demo), used to demonstrate how to build micro servics with [go-micro](https://github.com/go-micro/go-micro).**
 
+## Overview
+
 **Online Boutique** is a cloud-native microservices demo application.
 Online Boutique consists of a 11-tier microservices application. The application is a
 web-based e-commerce app where users can browse items,
 add them to the cart, and purchase them.
 
-**Google uses this application to demonstrate use of technologies like
-Kubernetes/GKE, Istio, Stackdriver, gRPC and OpenTelemetry**. This application
-works on any Kubernetes cluster, as well as Google
-Kubernetes Engine. It’s **easy to deploy with little to no configuration**.

-## Other Deployment Options
-
-- **Workload Identity**: [See these instructions.](docs/workload-identity.md)
-- **Istio**: [See these instructions.](docs/service-mesh.md)
-- **Anthos Service Mesh**: ASM requires Workload Identity to be enabled in your GKE cluster. [See the workload identity instructions](docs/workload-identity.md) to configure and deploy the app. Then, use the [service mesh guide](/docs/service-mesh.md).
-- **non-GKE clusters (Minikube, Kind)**: see the [Development Guide](/docs/development-guide.md)
-- **Memorystore**: [See these instructions](/docs/memorystore.md) to replace the in-cluster `redis` database with hosted Google Cloud Memorystore (redis).
-- **Cymbal Shops Branding**: [See these instructions](/docs/cymbal-shops.md)
-- **NetworkPolicies**: [See these instructions](/docs/network-policies/README.md)
