No compile instructions

[worthy7]

I tried to make a feature via this starter.

1. Download the template
2. Make a new feature or change the ID of color or hello feature
3. Error Blob /tmp/features-output-1699945273175/devcontainer-feature-.......tgz does not exist.

Via this comment devcontainers/features#752 (comment) it seems I should also have compiled something but I don't see those instructions in this feature-starter readme. So please can we make it clearer?

That sounds like a great suggestion.
If you have a moment, would you be willing to open a PR(s) to that readme? Thank you!
