+# Hungry Serpent Game
+
+Welcome to the Snake Game implemented in C++! This classic arcade game allows you to control a snake as it moves around the screen, eating food and growing longer with each meal. Be careful not to collide with the walls or yourself!
+
+## How to Play
+
+### Controls
+
+- **'a'**: Move the snake left
+- **'d'**: Move the snake right
+- **'w'**: Move the snake up
+- **'s'**: Move the snake down
+- **'x'**: Quit the game
+
+### Objective
+
+- Eat the 'F' (fruit) to grow your snake.
+- Avoid running into the walls or the snake's own tail, as it will result in game over.
+
+### Scoring
+
+- Each 'F' eaten increases your score by 10 points.
+- The game speed may increase as your score grows, making it more challenging.
+
+## Compiling and Running
+
+To compile and run the game, follow these steps:
+
+1. Compile the code using a C++ compiler like g++:
+   ```bash
+   g++ -o snake Hungry_Serpent.cpp
+
+2. Run the compiled program:
+   ```bash
+   ./snake
+   ```
+
+## Requirements
+
+- C++ compiler (e.g., g++)
+- Windows OS (for 'conio.h' library)
