+## Introduction
+Welcome to the 2-player Tic-Tac-Toe game! This classic game is designed for two players to compete against each other in a simple yet engaging way. It's a perfect choice for those who enjoy strategic thinking and friendly competition.
+
+## Game Rules
+Tic-Tac-Toe is played on a 3x3 grid. Two players take turns marking empty cells with their respective symbols:
+- Player 1: O
+- Player 2: X
+
+The goal of the game is to form a straight line (horizontal, vertical, or diagonal) of your symbol (X or O) before your opponent does. The player who achieves this first wins the game.
+
+## Getting Started
+To play the game, follow these steps:
+
+1. Clone this repository to your local machine or download the source code.
+2. Open a terminal or command prompt and navigate to the game's directory.
+
+## How to Play
+1. Run the game by executing the main script. For example, if you are using Python, you can run the game with the following command:
+   ```
+   python tictactoe.py
+   ```
+2. The game will display an empty 3x3 grid.
+3. Players will take turns entering the row and column where they want to place their symbol (X or O).
+4. The game will update the grid and display it after each move.
+5. Continue taking turns until one player wins or the game ends in a draw.
+
+## Winning
+A player wins by achieving one of the following conditions:
+- Completing a row (horizontally).
+- Completing a column (vertically).
+- Completing a diagonal line (either from the top-left to bottom-right or from top-right to bottom-left).
+
+The game will announce the winner and ask if you want to play again.
+
+## Draw
+If all cells on the grid are filled, and no player has achieved a winning condition, the game ends in a draw. It will inform you that the game is a draw and ask if you want to play again.
