-# Create a README.md
+# Rectangle Area Calculator 🟦
 
-If you need help with `Markdown`, check out [The Markdown Cheatsheet](https://www.markdownguide.org/cheat-sheet/)!
+This repository contains a simple Python script that calculates the area of a rectangle based on user input. It was created in Visual Studio as part of ATMS 523 Assignment 1 to demonstrate basic Python functionality and GitHub workflows.
 
-What should a good README.md look like? Check out these [guidelines](https://docs.github.com/en/repositories/managing-your-repositorys-settings-and-features/customizing-your-repository/about-readmes).
+## 🚀 How to Run

\ No newline at end of file
+You do **not** need Visual Studio Code to run this script. Here's how to do it using just Python and a terminal:
+
+### 🧰 Step 1: Install Python
+- Visit the [official Python website](https://www.python.org/downloads/) and download Python 3.x for your operating system.
+- During installation, make sure to check the box that says **“Add Python to PATH”** (Windows only).
+
+### 📁 Step 2: Download the Script
+- Go to this GitHub repository.
+- Click the green **“Code”** button and select **“Download ZIP”**.
+- Extract the ZIP file to a folder on your computer.
+
+### 📂 Step 3: Open a Terminal or Command Prompt
+- **Windows**: Press `Win + R`, type `cmd`, and hit Enter.
+- **macOS**: Open **Terminal** from Applications > Utilities.
+- **Linux**: Use your system’s terminal.
+
+### 📍 Step 4: Navigate to the Folder
+Use the `cd` command to move into the folder where the script is saved. For example:
+``bash
+cd Downloads/module-1-part-2-using-github-workflows-Key-Roberson-main
+
+### ▶️ Step 5: Run the Script
+Type the following command:
+python Simple_code.py
+
+### ✍️ Step 6: Follow the Prompts
+Enter the length and width when asked.
+The script will calculate and display the area of the rectangle.
+
+### 🧠 What It Does
+- Prompts the user to enter the length and width of a rectangle.
+- Calculates the area using a simple function.
+- Displays the result with formatted output.
+- Includes error handling for invalid input.
+
+### 🛠 Technologies Used
+Python 3
+Visual Studio Code (JupyterHub environment)
+Git & GitHub
+
+### 👩‍💻 Author
+Created by Kiara Roberson for ATMS 523 Assignment 1.
