Doubt of positional notation

This is called descriptive notation. In algebraic notation, the moves would be 1. Bd3 Kg7 2. Bg5 Kf7 3. Bf5.

Hi, I would like to ask someone to translate to me that explanation in the usual notation system, because I am not able to understand it correctly.
It is said: "Since the Black King is in the corner,
White can
play I B — Q 3 , K — Kt 2 ;
2 B — K Kt 5 , K — B 2 ;
3 B B 5 , and already the Black King is confined
to a few squares "
Thanks for your help in advance
