+# Dino Game
+
+## Description
+
+Dino Game is a simple yet addictive game built using Python and Pygame library. It's inspired by the classic Chrome Dinosaur game, where the player controls a dinosaur that must jump over obstacles to survive. The game features a dinosaur character, cactus obstacles, and a score system. I have created a simple clone of the game. Feel free to look through the code and run it.
+
+## Features
+
+- Control a dinosaur character to jump over obstacles.
+- Dodge incoming cactus obstacles to survive.
+- Track and display the player's score as they progress through the game.
+- Simple controls: Press the spacebar to make the dinosaur jump.
+- Press Enter to restart the game after a game over.
+
+## Installation
+
+1. Ensure you have Python installed on your system. You can download it from [python.org](https://www.python.org/).
+2. Clone this repository to your local machine:
+
+```
+git clone https://github.com/sahilrw/dino
+```
+
+3. Navigate to the project directory:
+
+```
+cd dino-game
+```
+
+4. Install the required dependencies using pip:
+
+```
+pip install pygame
+```
+
+## Usage
+
+1. Run the game by executing the following command:
+
+```
+python dino.py
+```
+
+2. Use the spacebar to make the dinosaur jump over obstacles.
+3. Avoid colliding with cactus obstacles to keep the game going.
+4. Your score will increase as you progress. Try to beat your high score!
+5. If the dinosaur collides with an obstacle, the game will end. Press Enter to restart and play again.
