Zero-to-jupyterhub-k8s: Ambiguous instructions in helm setup

[arokem]

Where is this line supposed to be executed?

Are you supposed to log into your cluster to do this? Into the head node? Into each of the worker nodes? Or do you do this on your local machine?

@arokem I run it locally.

Marking as "Help Wanted" for JupyterCon sprint. Add a clarifying statement that the helm init command is entered in the terminal of your local machine (similar to the terminal used for kubectl).
