@tanersener Thanks for this! As we don't use helm ourselves we can support this as best effort, but I would prefer if we also keep the existing non-helm resources in place. Could you change the PR to have both helm and non-helm manifests?

[tanersener]

@mikkeloscar Moved the helm folder under the docs. Now we have both manifests side by side.
