Exemption Request: I added a CLI integ test instead of framework-integ, because this is a change of CLI.

[lpizzinidev]

The implementation looks good.
I suggested some formatting adjustments for the documentation.

[tmokmss]

Hi @lpizzinidev thanks, I applied your suggestions. It'd be great if we had linter for markdown files too :)

[lpizzinidev]

Thanks 👍
