Vault HA Installation with TLS on KinD

Does anyone have clear repeatable instructions to install Vault in HA mode with TLS enabled. I seem to be running in circles and would appreciate any assistance that can be provided.

I am using the instructions at the link below; however, I do not know what to do with the configuration changes recommended. I attempted to alter my values.yaml, but Helm seemed to ignore the changes as if it was not looking at the ymal at all. Any assistance is appreciated. Thank you.

Example of installation command (values.yaml in directory)
helm install vault hashicorp/vault --namespace vault
