+# Running the tests
+
+Currently, overrides are needed for the cluster-api, kubeadm-bootstrap and kubeadm-control-plane providers. The override for the infra provider docker must be removed as it is generated locally by the e2e test script:
+
+	cmd/clusterctl/hack/local-overrides.py
+	rm -rf $HOME/.cluster-api/overrides/docker
+
+The entire test suite can be run using the script:
+
+	./run-e2e.sh
+
+To run specific tests, use the `GINKGO_FOCUS`
+
+	GINKGO_FOCUS="clusterctl create cluster" ./run-e2e.sh
+
+## Skip local build of CAPD
+
+By default, the a local capd image will be built and loaded into kind. This can be skipped as so:
+
+	SKIP_DOCKER_BUILD=1 ./run-e2e.sh
+
+You can also specifiy a pre-build image and skip the build:
+
+	SKIP_DOCKER_BUILD=1 MANAGER_IMAGE=gcr.io/my-project-name/docker-provider-manager-amd64:dev ./run-e2e.sh
