+# Snake Game
+
+## Overview
+In Snake, you must eat apples that appear. You will grow each time you eat an apple. Try to get the highest score possible and try not to hit the wall or yourself.
+
+
+## Controls
+Press `a` to move left
+
+Press `d` to move right
+
+Press `s` to move down
+
+Press `w` to move up
+
+
+## Installation
+
+1. **Clone the repository**
+
+   ```bash
+   git clone https://github.com/josharsh/100LinesOfCode
+   cd 100LinesOfCode/snake
+   ```
+
+2. **Install dependencies**
+
+   ```bash
+   pip install -r requirements.txt
+   ```
+   or
+   ```bash
+   pip install keyboard
+   ```
+
+> This installs only the dependencies required for the Snake game (e.g., `keyboard`).
