+# Calculator Project
+
+A simple and efficient calculator application for performing basic arithmetic operations.
+
+## Overview
+
+This calculator project provides a user-friendly interface for performing mathematical calculations. Whether you need to add, subtract, multiply, or divide numbers, this calculator has you covered with a clean and intuitive design.
+
+## Features
+
+- **Basic Arithmetic Operations**
+  - Addition (+)
+  - Subtraction (-)
+  - Multiplication (×)
+  - Division (÷)
+
+- **Additional Functionality**
+  - Clear/Reset functionality
+  - Decimal number support
+  - Error handling for invalid operations
+  - Responsive design
+
+## Getting Started
+
+### Prerequisites
+
+Before you begin, ensure you have the following installed:
+- A modern web browser (Chrome, Firefox, Safari, or Edge)
+- Or your preferred programming language runtime if using a specific implementation
+
+### Installation
+
+1. Clone the repository:
+   ```bash
+   git clone https://github.com/ethanyhou/testRepo.git
+   ```
+
+2. Navigate to the project directory:
+   ```bash
+   cd testRepo
+   ```
+
+3. Open the calculator application:
+   - For web-based version: Open `index.html` in your browser
+   - For other implementations: Follow the specific runtime instructions
+
+## Usage
+
+### Basic Operations
+
+1. Enter the first number
+2. Select an operation (+, -, ×, ÷)
+3. Enter the second number
+4. Press equals (=) to see the result
+
+### Example Calculations
+
+```
+5 + 3 = 8
+10 - 4 = 6
+7 × 6 = 42
+20 ÷ 4 = 5
+```
