The Chart.yaml is the mandatory metadata file for every Helm chart. The Helm Chart.yaml Generator builds a correct apiVersion v2 Chart.yaml from a short form so you do not have to recall the schema.
Set the name, version, appVersion and description, choose the type, and optionally add keywords, maintainers and dependencies. The output is a valid Chart.yaml you can drop into a chart directory.
Names and versions are validated. Everything runs locally and nothing is uploaded.
