+# Deploy GCE Ingress Controller
+
+Instructions for how to deploy an ingress controller in a cluster
+that was deployed by gcp-deployer
+
+1. Replace `<YOUR PROJECT ID>` and `<YOUR CLUSTER NAME>` in
+`ingress-controller.yml`.
+1. Run `kubectl create -f ingress-controller.yml`. This will create
+Kubernetes service account with the correct permissions in the cluster,
+a default backend for the ingress controller, and the glbc app
+
+Now you will be able to create ingress objects.
