What are the rules and benefits of performing a short castle in chess?

Performing a short castle in Chess involves moving the king two squares towards a rook and then moving the rook to the square next to the king. The benefits of short castling include improving the king's safety by moving it to a more secure position and connecting the rooks for better coordination. The rules for short castling include not being able to castle if the king has moved previously, if the rook has moved previously, if there are pieces between the king and rook, or if the king is in check.
