+# Mastermind Game
+
+A simple implementation of the classic Mastermind game in Python. Test your logical deduction skills by guessing a 4-digit number!
+
+## About the Game
+
+Mastermind is a classic board game where the player attempts to guess a secret code consisting of a sequence of colored pegs. In this implementation, you will be guessing a 4-digit number.
+
+## How to Play
+
+1. Run the game using a Python interpreter (Python 3.x).
+2. The program will generate a random 4-digit number for you to guess.
+3. Enter your guess as a 4-digit number.
+4. The game will provide feedback on how many digits you've guessed correctly and their positions.
+5. Keep guessing until you correctly guess the entire number!
