+## Running on minikube
+
+The e2e suite is also runnable on a minikube cluster. First spin up the minikube cluster manually with the desired provisioner, 
+then run `make run-local` to deploy OLM onto the cluster. Tests can be run by invoking ginkgo and passing the required command line
+arguments to the test suite. For example to run a specific test:
+
+```bash
+GO111MODULE=on GOFLAGS="-mod=vendor" go run github.com/onsi/ginkgo/ginkgo -focus "static provider" -v --progress ./test/e2e -- -namespace=operators -olmNamespace=olm -dummyImage=bitnami/nginx:latest
