+# Collaborative Drawing
+
+![drawing-demo](https://user-images.githubusercontent.com/5553757/189190756-21c2bc61-1816-488e-b2cd-bc910fece6d9.gif)
+
+A basic collaborative drawing application using Ypy and WebSockets. Left click on the canvas to leave a mark.
+
+## Getting Started
+
+1. Install Python dependencies:
+
+```
+pip install -r requirements.txt
+```
+
+2. Run the demo
+
+```
+python demo.py
+```
