 ## I'm getting Forbidden errors when trying to install Agones
 
+{{% feature expiryVersion="0.12.0" %}}
 Some troubleshooting steps:
 
 1. Run `kubectl describe clusterrolebinding | grep cluster-admin-binding- -A10` and make sure your email is in there. This may be
 _case sensitive_ so you may need to compare it to the case you used.
 1. In the [GKE tutorial]({{< ref "/docs/Installation#enabling-creation-of-rbac-resources" >}}) `gcloud config get-value accounts` 
 will return a lowercase email address, so if you are using a CamelCase email, you may want to type that in manually.
+{{% /feature %}}
+
+{{% feature publishVersion="0.12.0" %}}
+Ensure that you are running Kubernetes 1.12 or later, which does not require any special
+clusterrolebindings to install Agones.
+
+If you want to install Agones on an older version of Kubernetes, you need to create a
+clusterrolebinding to add your identity as a cluster admin, e.g.
+
+```bash
+# Kubernetes Engine
+kubectl create clusterrolebinding cluster-admin-binding \
+  --clusterrole cluster-admin --user `gcloud config get-value account`
+# Minikube
+kubectl create clusterrolebinding cluster-admin-binding \
+  --clusterrole=cluster-admin --serviceaccount=kube-system:default
+```
+
+On GKE, `gcloud config get-value accounts` will return a lowercase email address, so if
+you are using a CamelCase email, you may need to type it in manually.
