Annan fairy condition - pawns on 1st rank


Can pawns move to the first rank? For example Nf3 and pf2 -> g1? If it is legal - what happens with ir later - does it just stay here occupying the square with no way to move forward?

White pawns on first rank and black pawns on 8th rank are immobile.
Pawns that get to their promotion rank by a non-pawn move promote.
See example below.

Can't understand the solution as it is not in English!

Thanks, so if a white pawn is lets say on g1 (immobile), then it doesn't attack f2 and h2. So, black king can move into these squares, right?
