[feat]: Example of custom registry usage

[RegiByte]

Feature description

Hey can we get an example or documentation about how to use a custom registry with the CLI to install components from a custom design system?

Affected component/components

No response

Additional Context

Inspired by Jack Herrington's latest video: https://www.youtube.com/watch?v=NP2ULDZxpd0

Basically, he created a tool that semi-automatically creates a registry of components based on a git repo history

I would like to know if we can have an official way of doing this, I'm pretty sure a LOT of people would benefit from this.
I believe it would be similar to what is being done on v0 with the generated components.

Let me know if I can help on this!
