Is your feature request related to a problem? Please describe.
I was not able to get the csi driver working with microk8s due to permission issues (securityContext doesnt help)

Describe the solution you'd like in detail
Need to add an extra section in the tutorial describing how to configure the helm chart values for microk8s users. This is what i needed to change to get it to work:

helm upgrade --install aws-mountpoint-s3-csi-driver
--namespace kube-system
--set node.kubeletPath=/var/snap/microk8s/common/var/lib/kubelet
aws-mountpoint-s3-csi-driver/aws-mountpoint-s3-csi-driver

Glad to hear you got this working and thanks for the information. Microk8s isn't officially support and it's not something we've tested. This is definitely something that can go in the documentation though, with the caveat that it's not part of the regression test suite.
