+# Kubernetes Code Copy Area
+
+This directory is the copy of original types from the main 
+[kubernetes/kubernetes repo](https://github.com/kubernetes/kubernetes) with 
+maintaining original packages structure. The purpose of this package is to
+avoid depending on the entire main repo and copy only necessary types as needed.
+
+The types in this directory should be treated as read-only, and any necessary
+changes should be addressed in the original repository. If there are some 
+specific changes needed to be made for Service Catalog, the type should be moved
+out of this directory to the appropriate one first.
+
+## Updating dependencies to the latest Kubernetes release
+
+When updating dependencies on 
+[k8s.io/apimachinery](https://github.com/kubernetes/apimachinery),
+[k8s.io/client-go](https://github.com/kubernetes/client-go), 
+[k8s.io/apiserver](https://github.com/kubernetes/apiserver)
+and other top-level Kubernetes repositories, we need to overwrite the types in
+this directory with the latest version from the corresponding release of
+[k8s.io/kubernetes](https://github.com/kubernetes/kubernetes) to keep the files
+in sync.
+
+## Long-term plan
+
+In the long term the packages used by Kubernetes-based projects will be moved
+from the main repo to separate top-level repositories, [k8s.io/common](https://github.com/kubernetes/common)
+and [k8s.io/utils](https://github.com/kubernetes/utils). Once it is done, we can
+eventually switch to those packages and drop this directory.
