	ReleaseName string
	// Chart is the loaded chart. Use `LoadChart`.
	Chart *Chart
	// Values are the custom values to be used on the chart template..
	Values map[string]interface{}
	// IncludeCRDs when enabled will template/render the CRDs.
	IncludeCRDs bool
	// Namespace is the namespace used to render the chart.
	Namespace string
	// ShowFiles is a list of files that can be used to only template the provided files,
	// by default it will render all.
	// This can be handy on specific use cases like unit tests for charts.
	ShowFiles []string
}

TemplateConfig is the configuration for Helm Template rendering.
