-## Assumptions and prerequisites
+# Assumptions and prerequisites
 
 - You are using JWT authentication to your clusters (i.e. Downward API tokens mounted to pods)
 - If using external clusters, you must populate cluster annotation with its Certificate Authority
 
-## Usage
-
-1. Deploy the argocd-applicationset-namespaces-generator-plugin from `testdata/manifest.yaml`.
-
-2. Deploy the ApplicationSet YAML from `testdata/appset.yaml`.

-Here's an example to use together with clusters generator via matrix generator:

+# Usage
 
-# Testing
+## Local
 
 ```bash
 go run ./... -v=4 --log-format=json server --local
 curl -X POST -H "Content-Type: application/json" -d @testdata/request.json http://localhost:8080/api/v1/getparams.execute
 ```
+
+## In Cluster
+
+1. Deploy the argocd-applicationset-namespaces-generator-plugin Deployment.
+
+   ```console
+   kubectl apply -f testdata/manifest.yaml
+   ```
+
+2. Deploy the ApplicationSet YAMLs.
+
+   ```console
+   kubectl apply -f testdata/project-airplanehsiao-appset.yaml
+   kubectl apply -f testdata/project-hsiaoairplane-appset.yaml
+   ```
+
+3. Create ArgoCD ApplicationProjects.
+
+   ```console
+   argocd proj create project-hsiaoairplane
+   argocd proj create project-airplanehsiao
+   ```
+
+4. Create the project "hsiaoairplane" namespaces.
+
+   ```console
+   kubectl create namespace foo
+   kubectl label namespace foo project=hsiaoairplane --overwrite=true
+   kubectl create namespace foobar
+   kubectl label namespace foobar project=hsiaoairplane --overwrite=true
+   ```
+
+5. Create the project "airplanehsiao" namespaces.
+
+   ```console
+   kubectl create namespace bar
+   kubectl label namespace bar project=airplanehsiao --overwrite=true
+   kubectl create namespace barfoo
+   kubectl label namespace barfoo project=airplanehsiao --overwrite=true
+   ```
+
+6. Access the ArgoCD GUI.
+
+   ```console
+   argocd admin dashboard -n argocd
+   ```
+
+7. Open the browser http://localhost:8080/
