+## Security Limitations
+
+With the `none` driver, minikube has limited container isolation abilities. Applications running in a container may be able to access your host filesystem. Through using a container escape vulnerability such as [CVE-2019-5736](https://access.redhat.com/security/vulnerabilities/runcescape), they may also be able to execute arbitrary code on your host.
+
+When using the `none` driver, it is highly recommended that your host is isolated from the rest of the network using a firewall.
+
+Additionally, minikube with the `none` driver has a very confusing permissions model, as some commands need to be run as root ("start"), and others by a regular user ("dashboard"). In a future release, we intend to disallow running `minikube`, and instead call into `sudo` when necesarry to avoid permissions issues.

+The `none` driver now supports uninstallation via `minikube delete`. Please note that it will not fully remove /etc/kubernetes, since it does not track which files in /etc/kubernetes existed before the installation.
