+# Rock-Paper-Scissors Game
+
+> A Python implementation of the classic Rock-Paper-Scissors game.
+
+## Description
+
+Rock-Paper-Scissors is a simple hand game usually played between two people. Each player simultaneously forms one of three shapes with their hand. The possible shapes are "rock" (a fist), "paper" (an open hand), and "scissors" (a fist with the index and middle fingers extended, forming a V). The winner is determined by the rules: rock beats scissors, scissors beats paper, and paper beats rock.
+
+## How to Play
+
+1. Run the main script to start the game:
+
+2. The game will prompt you to enter your choice: rock, paper, or scissors.
+
+3. The computer will randomly choose its option.
+
+4. The winner will be displayed on the screen.
