Document a setup using a ReadWriteMany storage that is resilient and scallable.
Maybe use part of pypicloud in order to use S3 or GCS backend storage.

Adding the repo

To add the repo to helm with the name owkin:

$ helm repo add owkin https://owkin.github.io/charts

Installing the Chart

To install the chart with the release name my-release:

$ helm install --name my-release owkin/pypiserver

Upgrading the Charts

Updating the chart is as straightforward as updating the helm release

$ helm upgrade my-release owkin/pypiserver
