+## E2E testing with kuttl
+
+[Kuttl](https://kuttl.dev/) is an end to end testing framework for Kubernetes operators. We hope to provide full test coverage for the Frontend Operator with kuttl.
+
+To run the kuttl tests you'll need to be running the operator and Clowder in minikube as shown in the directions above. You also need to make sure you [have kuttl installed on your machine](https://kuttl.dev/docs/cli.html#setup-the-kuttl-kubectl-plugin).
+
+Once all that is in place you can run the kuttl tests:
+
+```bash
+$ make kuttl
+```
+Friendly reminder: make sure you have the frontend operator runnning (`make run-local`) before you run the tests or they will never work and you'll go nuts trying to figure out why.
