Describe the solution you'd like

To ensure that changes made to the Helm chart are always in sync with the README.md file, it would be nice to generate them automatically. There are some libs that make it possible:

• https://github.com/norwoodj/helm-docs,
• or https://github.com/bitnami-labs/readme-generator-for-helm.

It may require a small changes to the comment formatting, though.
