-In some cases, you might want to clean up some resources after the tests, while in other cases, you might want to skip cleaning up test applications for further usage. The following flags are available to customize cleanup.
+- `--ipv6`: Enables creating a KinD cluster with IPv6 networking and run E2E tests on it.
 - `--cleanup`: Cleans up the KinD cluster and local registry after tests are completed.
 - `--skip-cleanup-apps`: Skips the cleanup of test applications after the tests have been executed.
