+## Using etcd-operator-builder
+### Building the Builder
+For convenience and easy of building, a Dockerfile has been provided to create an
+etcd-operator-builder image.  This image contains a fully configured go envrionment
+used for fetching dependencies and building the different etcd-operator binaries.
+
+To build the etcd-operator-builder image, you first need to have docker installed.
+
+Once installed, set the IMAGE environment variable to the desired name:
+```
+export IMAGE=etcd-operator-builder
+```
+
+Now, run the build script to generate the etcd-operator-builder:
+```
+./hack/build/e2e/builder/build
+```
+
+Once completed, the etcd-operator-builder:latest image should be available for use.
+
+
+### Updating the Dependencies Using the Builder
+Updating dependencies using this image can be performed by running the ci get_dep script:
+```
+./hack/ci/get_dep
+```
+
+
+### Building etcd-operator Using the Builder
+Then build the project using the image:
+```
+./hack/build/build
+```
+
+
+## Creating the etcd-operator Docker Image
+Finally, build the etcd-operator image:
+```
+export IMAGE=etcd-operator
+docker build --tag "${IMAGE}" -f hack/build/Dockerfile . 1>/dev/null
+```
