$ helm repo add crossview https://corpobit.github.io/crossview
Error: looks like "https://corpobit.github.io/crossview" is not a valid chart repository or cannot be reached: failed to fetch https://corpobit.github.io/crossview/index.yaml : 404 Not Found
helm repo add crossview https://crossplane-contrib.github.io/crossview works.
Just a doc update required?
