[Feature Request] Readme generation (Semi Storybook support?)

[softmarshmallow]

Generation of documentation outside of the executable code (comment), A README.md or component.stories.mdx With preview included will help developers to manage their project structure & component hierarchy.

Challenges.

• What happens when the component gets splitted? (What if source A and documentation A' does not match no longer?
• What happens when user customize the documentation content?
