+## 🚀 Deployment Paths
+
+### **Path 1: PWA (Fastest - RECOMMENDED)** ⭐
+- **Time**: 5 minutes
+- **Setup**: `python app.py` → open on browser → install
+- **Best for**: Testing, development, quick deployment
+- **Pros**: No build needed, instant updates, works everywhere
+- **Cons**: Requires WiFi connection to server
+
+### **Path 2: Docker (Most Scalable)**
+- **Time**: 15 minutes (first build)
+- **Setup**: `docker build . && docker run -p 7860:7860 hearthnet`
+- **Best for**: Production deployment, scaling, CI/CD
+- **Pros**: Reproducible, isolated, easy scaling
+- **Cons**: Requires Docker installation
+
+### **Path 3: Android APK (Native App)**
+- **Time**: Already built! 3 minutes install
+- **Setup**: Copy APK to phone and tap to install
+- **Best for**: Play Store distribution, offline-first mobile
+- **Pros**: Native app, Play Store compatible, offline capable
+- **Cons**: Debug build (not signed), larger file size
+
+### **Path 4: Python CLI (Development)**
+- **Time**: 10 minutes
+- **Setup**: `pip install -r requirements.txt && python app.py`
+- **Best for**: Development, testing, node operation
+- **Pros**: Full control, easy debugging
+- **Cons**: Requires Python environment
