<p>Is it correct to say that a scaffolding in Helm Chart is a Chart based on another Chart with your own customization?</p>
<p>If that's correct why don't we just customize values.yaml instead? If we need to change the configuration why don't we write a new Chart instead?</p>
<p>what are the use cases for creating a scaffolding?</p>

<p><code>helm create xyz</code> just builds you a starting structure in whuch you can develop the chart needed for your <code>xyz</code> project.  It has no relationship to any existing chart.</p>
<p>The use-case is 'programmer who prefers not to start with a blank sheet of paper'.</p>
