-### Accessing the Application
-
-#### Option 1: Port Forwarding
+### **2. Federated Learning Process:**
+1. **Client Registration**: Banks register with the federated server
+2. **Local Training**: Each bank trains on their private data (simulated)
+3. **Model Updates**: Only model weights are shared (not raw data)
+4. **Aggregation**: Server combines updates using FedAvg algorithm
+5. **Global Model**: Updated model distributed to all participants
+6. **Predictions**: Users get credit scores from the collaborative model
+
+### **3. Privacy Protection:**
+- 🔒 **Data Never Leaves**: Each bank's data stays completely local
+- 🔒 **Model Updates Only**: Only gradients/weights are shared
+- 🔒 **No Central Database**: No single point of data collection
+- 🔒 **Collaborative Learning**: Multiple banks improve the model together
+
+## 🎮 **User Experience**

+## 🔧 **How It Works**
+
+### **1. Federated Learning Process:**
+- **Client Registration**: Banks register with the federated server
+- **Local Training**: Each bank trains on their private data (simulated)
+- **Model Updates**: Only model weights are shared (not raw data)
+- **Aggregation**: Server combines updates using FedAvg algorithm
+- **Global Model**: Updated model distributed to all participants
+- **Predictions**: Users get credit scores from the collaborative model
+
+### **2. Privacy Protection:**
+- 🔒 **Data Never Leaves**: Each bank's data stays completely local
+- 🔒 **Model Updates Only**: Only gradients/weights are shared
+- 🔒 **No Central Database**: No single point of data collection
+- 🔒 **Collaborative Learning**: Multiple banks improve the model together
+
+### **3. Interactive Features:**
+- **Start/Stop Clients**: Control client participation
+- **Training Rounds**: Manually trigger training rounds
+- **Real-time Metrics**: Watch accuracy improve over time
+- **Live Visualizations**: See training progress charts
+- **Debug Information**: Monitor system status and logs
+
+## 🎮 **How to Use the Demo**
+
+### **Step 1: Access the Demo**
+Visit: https://huggingface.co/spaces/ArchCoder/federated-credit-scoring
+
+### **Step 2: Try Credit Scoring**
+1. Enter 32 customer features (or use default values)
+2. Click "Predict Credit Score"
+3. Get prediction from the federated model
+
+### **Step 3: Start Federated Learning**
+1. Click "Start Client" in the sidebar
+2. Click "Start Training" to begin federated rounds
+3. Watch the model accuracy improve in real-time
+4. Use "Simulate Round" to manually progress training
+
+### **Step 4: Monitor Progress**
+- Check "System Status" for current metrics
+- View "Training Progress" for live updates
+- Monitor "Debug Information" for system logs
+

+### 🚀 **Complete Federated Learning System**
+
+This demo showcases a **fully functional federated learning system** running entirely on Hugging Face Spaces:
+
+#### **What's Running:**
+- ✅ **Federated Server**: Coordinates training across multiple clients
+- ✅ **Client Simulator**: Participates in federated learning rounds
+- ✅ **Model Aggregation**: FedAvg algorithm for combining model updates
+- ✅ **Privacy Protection**: No raw data sharing between participants
+- ✅ **Real-time Training**: Live training progress visualization
+- ✅ **Credit Scoring**: Predictions from the federated model
+
+#### **How It Works:**
+1. **Client Registration**: Banks register with the federated server
+2. **Local Training**: Each client trains on their private data
+3. **Model Updates**: Only model weights are shared (not data)
+4. **Aggregation**: Server combines updates using federated averaging
+5. **Global Model**: Updated model is distributed to all clients
+6. **Predictions**: Users get credit scores from the collaborative model
+
+#### **Privacy Benefits:**
+- 🔒 **Data Never Leaves**: Each bank's data stays local
+- 🔒 **Model Updates Only**: Only gradients/weights are shared
+- 🔒 **No Central Database**: No single point of data collection
+- 🔒 **Collaborative Learning**: Multiple banks improve the model together
+
+#### **Production Ready Features:**
+- 🏗️ **Kubernetes Deployment**: Ready for production scaling
+- 🐳 **Docker Containers**: Containerized for easy deployment
+- 📊 **Monitoring**: Real-time training metrics and health checks
+- 🔧 **Configuration**: Flexible config management
+- 🧪 **Testing**: Comprehensive test suite
+
+**This is a complete, production-ready federated learning system!** 🎯
