+## Local clusters
+
+It can be much faster to iterate on a local cluster instead of a cloud-based one.  To start a local cluster, you can run:
+
+```sh
+# The PATH construction is needed because PATH is one of the special-cased
+# environment variables not passed by sudo -E
+sudo PATH=$PATH hack/local-up-cluster.sh
+```
+
+This will start a single-node Kubernetes cluster than runs pods using the local docker daemon.  Press Control-C to stop the cluster.
+
+### E2E tests against local clusters
+
+In order to run an E2E test against a locally running cluster, use the `e2e.test` binary built by `hack/build-go.sh`
+directly:
+
+```sh
+export KUBECONFIG=/path/to/kubeconfig
+e2e.test --host=http://127.0.0.1:8080
+```
+
+To control the tests that are run:
+
+```sh
+e2e.test --host=http://127.0.0.1:8080 --ginkgo.focus="Secrets"
+```
