Precise in the documentation that one can add the nrdxp cache with sudo if the current user is not trusted.
This is related to this issue: #287.

That could be a good change for one of the guides in the start section.

For posterity and context, I link #98 which expands on the possible future of cache configuration within the context of flakes (nixConfiguration.subsituters). That seems not yet working properly.

here it is!
I didn't resolve #98 with this one, to resolve it I think that a note should probably be made but in another file talking about configuration or an annex with things that do not work as of now if at all necessary
