+This is an experimental driver. Please use it only for experimental reasons until it has reached maturity. For a more reliable minikube experience, use a non-experimental driver, like [Docker]({{< ref "/docs/drivers/docker.md" >}}).
 
 ## Usage
 
-Start a cluster using the podman driver:
+It's recommended to run minikube with the podman driver and [CRI-O container runtime](https://https://cri-o.io/): 
 
 ```shell
-minikube start --driver=podman
+minikube start --driver=podman --container-runtime=cri-o

+Alternatively, start minikube with the podman driver only:

-The podman driver is another kubernetes in container driver for minikube. similar to [docker](https://minikube.sigs.k8s.io/docs/drivers/docker/) driver. The podman driver is  experimental, and only supported on Linux and macOS (with a remote podman server).
+The podman driver is an alternative container runtime to the [Docker]({{< ref "/docs/drivers/docker.md >}}) driver.
 
 ## Requirements
 
-- Install [Podman](https://podman.io/getting-started/installation) 
-- amd64 system 
+- Linux or macOS operating systems on amd64 architecture 
+- Install [podman](https://podman.io/getting-started/installation.html)
 
-## Try it with CRI-O container runtime.
-
-```shell
-minikube start --driver=podman --container-runtime=cri-o
-```

 ## Known Issues
 
 - Podman driver is not supported on non-amd64 architectures such as arm yet. For non-amd64 archs please use [other drivers]({{< ref "/docs/drivers/_index.md" >}}) 
+- Podman requirements passwordless running of sudo. If you run into an error about sudo, do the following: 
+
+```shell
+$ sudo visudo
+```
+Then append the following to the section *at the very bottom* of the file where `username` is your user account.
+
+```shell
+username ALL=(ALL) NOPASSWD: /usr/bin/podman
+```
+
+Be sure this text is *after* `#includedir /etc/sudoers.d`. To confirm it worked, try: 
+
+```shell
+sudo -k -n podman version
+```
+
+## Troubleshooting
+
+- Run `minikube start --alsologtostderr -v=7` to debug errors and crashes
