+# Rock Paper Scissors Game
+
+This Python script allows you to play the classic game of Rock Paper Scissors against the computer. The game continues until the user decides to stop playing.
+
+## How to Play
+
+1. Run the Python script.
+2. Enter your choice (rock, paper, or scissors) when prompted.
+3. The computer will randomly select its choice.
+4. The winner of the round will be determined based on the choices.
+5. You can choose to play again or exit the game.
+
+## Implementation Details
+
+- The script imports the `random` module to enable random selection of the computer's choice.
+- It defines a list `options` containing the possible choices: "rock", "paper", and "scissors".
+- Variables `score` and `rounds_played` are initialized to keep track of the player's score and the number of rounds played.
+- The game is played in a `while` loop, which continues until the player decides to stop.
+- After each round, the result is printed, and the score and rounds played are updated accordingly.
+- If the player inputs an invalid choice, they are prompted to enter a valid one.
+- After each round, the player is asked if they want to play again. If not, the game displays the final score and the number of rounds played.
