+h3 General rules
+
+ul
+ li.
+ The three farthest ranks are the promotion zone.
+ Every starting piece except the king and queen may promote by moving into
+ the promotion zone or moving from within the promotion zone.
+ li.
+ However, only one of each major piece (queen, mortar, archbishop, or
+ general) can be out on each side at a time.
+ li.
+ Captured pieces may be dropped back into the board as your own piece.
+ Pieces can be dropped anywhere within the first 5 ranks.
+ li.
+ When promoted pieces are captured, they revert to their unpromoted side.
+ This is the only way that a queen becomes a duchess.
+
+p Note: pawns cannot promote if capturing en passant.
