+# sample-controller
+
+This repository implements a simple controller for watching Foo resources as
+defined with a CustomResourceDefinition (CRD).
+
+It makes use of the generators in [k8s.io/code-generator](https://github.com/kubernetes/code-generator)
+to generate a typed client, informers, listers and deep-copy functions. You can
+do this yourself using the `./hack/update-codegen.sh` script.
+
+The `update-codegen` script will automatically generate the following files &
+directories:
+
+* `pkg/apis/samplecontroller/v1alpha1/zz_generated.deepcopy.go`
+* `pkg/client/`
+
+Changes should not be made to these files manually, and when creating your own
+controller based off of this implementation you should not copy these files and
+instead run the `update-codegen` script to generate your own.
+
+# Purpose
+
+This is an example of how to build a kube-like controller with a single type.
+
+# Compatibility
+
+HEAD of this repository will match HEAD of k8s.io/apimachinery and
+k8s.io/client-go.
+
+# Where does it come from?
+
+`sample-controller` is synced from
+https://github.com/kubernetes/kubernetes/blob/master/staging/src/k8s.io/sample-controller.
+Code changes are made in that location, merged into k8s.io/kubernetes and
+later synced here.
