Summarize this article:

The first thing that each player does at the start of his or her turn is to draw a card from the pile. Cards cannot be taken from the discard pile. Only the face down cards may be drawn. When you draw a card, read what it says to do and follow the directions.  Some cards have special rules that allow you to split the move between two pawns, take the place of an opponent’s pawn, or move backwards. You need to draw either a 1 or 2 to make your first move. If you draw a card that will advance one or more of your pawns past another player’s pawns or past your own pawns, then you can jump over them. Do not move other players’ pawns if you jump them, just move to the space that your card allows you to go to. If you land on a space that is occupied by an opponent’s pawn, then you will need to bump it back to the START space. Two pawns can never occupy the same space in Sorry. If you draw a card that would move one of your pawns to a space you already own, you do not get to move that turn. Leave all of your pawns where they are and let the next player take his or her turn. If you land on a SLIDE triangle that is not the same color as the pawns you have chosen, then you get to slide to the circle at the end of the triangle. As you slide, bump any other pawns (including your pawns) back to the START space. If the triangle is the same color as your pawns, do not slide. Just stay put on the triangle and move as usual during your next turn. Each player has a SAFETY ZONE that is the same color as his or her pawns. If the card that you draw allows you to do so, you may move into your SAFETY ZONE. Doing so may protect you from losing the progress you have made with one of your pawns. On a subsequent turn, you can move your pawn back out of the SAFETY ZONE if the card allows you to do so. It is possible that you and your fellow players will draw all of the cards in the deck before the end of the game. If you do, then simply shuffle the deck and replace the cards face down on the card spot of the Sorry board. To win Sorry, you need to get all of your pawns to the home space. Getting your pawns home sounds simple, but it may take time because other players will bump you back to START. You also need to draw the exact number of spaces between a pawn and your home space in order to get there. The number cannot be higher than the amount of spaces between your pawn and the HOME space.

Summary:
Draw a card at the beginning of each turn. Jump over pawns that belong to you or to other players. Bump your opponents’ pawns if you land on an occupied space. Slide if you land on a SLIDE triangle. Observe the SAFETY ZONE. Shuffle the discard pile if you use up all of the cards before the game is over. Get all of your pawns to the HOME space to win the game.
