+## How to run
+
+1. Clone the repository
+   ```
+   git clone [email protected]:GDSC-RCCIIT/General-Purpose-Scripts.git
+   ```
+2. Install the script requirements
+   ```
+   pip install -r requirements.txt
+   ```
+3. Navigate to `QR and Barcode Scanner` directory
+   ```
+   cd General-Purpose-Scripts/scripts/QR and Barcode Scanner
+   ```
+4. Replace "frame.png" with the image path of the QR/Barcode or, with the name of the png file if it is in the same directory as the script.
+   ### Note
+   The png file can also be placed in the same directory as the script and renamed to "frame.png" to avoid making changes to the code.
+5. Run the script to scan the QR/Barcode
+   ```
+   python scanner.py
+   ```
