 ### Extract CUE templates directly from Kubernetes Go source
 
+In order for `cue get go` to generate the CUE templates from Go sources, you first need to have the sources locally:
+
+```
+$ go get k8s.io/api/apps/v1
+$ go get k8s.io/api/extensions/v1beta1
+$ go get k8s.io/api/apps/v1beta1
+```
+
 ```
 $ cue get go k8s.io/api/core/v1
 $ cue get go k8s.io/api/extensions/v1beta1
