+# 🎚️ Gesture Volume Control
+
+Control your system volume with hand gestures using your webcam!  
+This project uses **OpenCV**, **MediaPipe**, and **pycaw** to detect your hand in real time and map the distance between your thumb and index finger to system volume.
+
+## ⚙️ Requirements
+```bash
+pip install opencv-python mediapipe pycaw comtypes
+```
+
+Check out my github: [10mudassir007](https://github.com/10mudassir007)
