+To run the end-to-end tests, you'll need [`kind`](https://kind.sigs.k8s.io) and [`chainsaw`](https://kyverno.github.io/chainsaw). Refer to their documentation for installation instructions.
 
 Once they are installed, the tests can be executed with `make prepare-e2e`, which will build an image to use with the tests, followed by `make e2e`. Each call to the `e2e` target will setup a fresh `kind` cluster, making it safe to be executed multiple times with a single `prepare-e2e` step.
