+Release Workflow
+======
+
+This docs describes the release process of kube-etcd-controller public docker image.
+
+## Prerequisites
+
+Make sure following tools are installed:
+- glide
+- docker
+
+Make sure you have a quay.io account.
+
+## Build image
+
+Make sure your working directory is root of "kube-etcd-controller/".
+
+Install dependency if none exists:
+```
+$ glide install
+```
+You should see "vendor/".
+
+Build docker image
+```
+$ docker build --tag quay.io/coreos/kube-etcd-controller:${TAG} -f hack/release/Dockerfile .
+```
+`${TAG}` is the release tag. For example, "v0.0.1", "latest".
+We also need to create a corresponding release on github with release note.
+
+## Push to quay.io
+
+Login to quay.io using docker if not done before:
+```
+$ docker login quay.io
+```
+Follow the prompts.
+
+Push docker image to quay.io:
+```
+$ docker push quay.io/coreos/kube-etcd-controller:${TAG}
+```
+`${TAG}` is the same as above.
