 1.  Install Istio:
     ```bash
+    kubectl apply --filename https://github.com/knative/serving/releases/download/v0.2.2/istio-crds.yaml && \
     kubectl apply --filename https://github.com/knative/serving/releases/download/v0.2.2/istio.yaml
     ```
+	Note: the resources (CRDs) defined in the `istio-crds.yaml`file are
+	also included in the `istio.yaml` file, but they are pulled out so that
+	the CRD definitions are created first. If you see an error when creating
+	resources about an unknown type, run the second `kubectl apply` command
+	again.

 1.  Label the default namespace with `istio-injection=enabled`:
     ```bash
     kubectl label namespace default istio-injection=enabled
