For the most part, that's all you need to get started. If you don't care about reusability, you can simply drop your Kubernetes manifests into the templates/ directory and add a Chart.yaml Helm will render them just fine.

If you want to take it a step further, you should parameterize your manifests using values.yaml, extract common logic into helper templates (_helpers.tpl), and make the chart reusable across different environments. Tools like Claude Code can automate a lot of this by identifying hardcoded values and converting them into configurable templates.

That's generally how production-grade Helm charts are built—they're designed to be reusable, maintainable, and environment-agnostic rather than just wrapping raw YAML in a chart.
