+# Wi-Fi Password Extractor + QR Code Generator
+
+A small Windows-only Python utility that extracts saved Wi-Fi profiles (SSIDs) and their passwords from the current machine and optionally generates QR codes for each network so other devices can scan and join easily.
+
+> ⚠️ **Important — Use ethically**  
+> Only run this script on machines you own or have permission to inspect. Do NOT use it to access networks that you are not authorized to access.
+
+---
+
+## Features
+
+- Lists saved Wi-Fi SSIDs on the current Windows machine.
+- Prints stored passwords (if present).
+- Generates QR code PNG files for networks with passwords.
+- Saves QR images to a local folder named `wifi_qr_codes`.
+
+---
+
+## Requirements
+
+- Python 3.8+ (recommended)
+- Windows (uses `netsh wlan` commands)
+- See `requirements.txt` for Python package dependencies.
+
+Install dependencies:
+
+```bash
+# Using pip
+python -m pip install -r requirements.txt
+
+# or directly
+python -m pip install qrcode[pil]
+```
