+# GRPC routes
+
+!!! warning
+    We tested grpc support only by looking at resources state as traffic providers didn't support grpc well at the moment of development but it would be great if you contribute a real example
+
+To use GRPCRoute:
+
+1. Install your traffic provider
+2. Install [GatewayAPI CRD](https://gateway-api.sigs.k8s.io/guides/#installing-gateway-api) if your traffic provider doesn't do it by default
+3. Install [Argo Rollouts](https://argoproj.github.io/argo-rollouts/installation/)
+4. Install [Argo Rollouts GatewayAPI plugin](installation.md)
+5. Create stable and canary services
+6. Create GRPCRoute resource according to the GatewayAPI and your traffic provider documentation
+```yaml
+apiVersion: gateway.networking.k8s.io/v1alpha2
+kind: GRPCRoute
+metadata:
+  name: first-grpcroute
+  namespace: default
+spec:
+  parentRefs:
+    - name: traefik-gateway # read documentation of your traffic provider to understand what you need to specify here
+  rules:
+    - backendRefs:
+        - name: argo-rollouts-stable-service # stable service you have created on the 5th step
+          port: 80
+        - name: argo-rollouts-canary-service # canary service you have created on the 5th step
+          port: 80
+```
+7. Create Rollout resource
+```yaml
+apiVersion: argoproj.io/v1alpha1
+kind: Rollout
+metadata:
+  name: rollouts-demo
+  namespace: default
+spec:
+  replicas: 2
+  strategy:
+    canary:
+      canaryService: argo-rollouts-canary-service
+      stableService: argo-rollouts-stable-service
+      trafficRouting:
+        plugins:
+          argoproj-labs/gatewayAPI:
+            grpcRoute: first-grpcroute # grpcroute you have created on the 6th step
+            namespace: default # namespace where your grpcroute is
+      steps:
+        - setWeight: 30
+        - pause: { duration: 2 }
+  revisionHistoryLimit: 1
+  selector:
+    matchLabels:
+      app: rollouts-demo
+  template:
+    metadata:
+      labels:
+        app: rollouts-demo
+    spec:
+      containers:
+        - name: rollouts-demo
+          image: argoproj/rollouts-demo:red
+          ports:
+            - name: http
+              containerPort: 8080
+              protocol: TCP
+          resources:
+            requests:
+              memory: 32Mi
+              cpu: 5m
