Show warning to use the device normally once if needed

[MagicLike]

Is your feature request related to a problem? Please describe.
As seen in among others the Pixel 7 Lineage installation guide

Describe the solution you'd like
Add a warning via metadata to certain configs or make it a general checkmark before starting with the installation (next to battery is charged, etc.)

Can be done with brand or just with notes metadata, isn't it?

I would probably add it to the requirements section.
