+## Testing Locally Using Kind
+
+> NOTE: You can install [kind from here](https://kind.sigs.k8s.io/docs/user/quick-start/#installation)
+
+The following will create a new cluster called "podinfo" and configure host ports on 80 and 443. You can access the
+endpoints on localhost. The example also deploys cert-manager within the cluster along with a self-signed cluster issuer
+used to generate the certificate to validate the secure port.
