+- Use type hints for function parameters and return values
+- Write docstrings for all public functions and classes
+- Keep functions focused and under 50 lines when possible
+
+```python
+def process_csi_data(csi_packet: CSIPacket) -> CIRResult:
+    """
+    Process CSI packet and convert to Channel Impulse Response.
+    
+    Args:
+        csi_packet: CSI packet containing subcarrier data
+        
+    Returns:
+        CIRResult containing delay and amplitude information
+        
+    Raises:
+        ValueError: If CSI data is invalid
+    """
+    # Implementation here
+    pass
+```
+
+#### C++
+- Follow [Google C++ Style Guide](https://google.github.io/styleguide/cppguide.html)
+- Use meaningful variable and function names
+- Add comments for complex algorithms
+- Include error handling and logging
+
+```cpp
+/**
+ * @brief Process CSI data and convert to CIR
+ * @param csi_data Input CSI data
+ * @return CIR result with delay and amplitude
+ * @throws std::runtime_error if data is invalid
+ */
+CIRResult processCSIData(const CSIData& csi_data) {
+    // Implementation here
+}
+```

+    "window_height": 1200,
+    "theme": "dark",
+    "auto_save": true
+  }
+}
+```
+
+## Network Protocols
+
+### Device Communication Protocol
+
+#### Connection Establishment
+1. Device discovery via UDP broadcast on port 8080
+2. TCP connection establishment on device-specific port
+3. Handshake protocol for capability negotiation
+4. Data streaming with protocol headers
+
+#### Message Format
+```
+[Header: 8 bytes][Payload: variable length]
+Header: [MessageType: 2 bytes][Length: 4 bytes][Flags: 2 bytes]
+```
+
+#### Message Types
+- `0x0001` - Device Info
+- `0x0002` - Data Stream
+- `0x0003` - Control Command
+- `0x0004` - Status Update
+- `0x0005` - Error Report
+
+### Azure REST API Integration
+
+#### Authentication
+- OAuth 2.0 client credentials flow
+- Bearer token authentication
+- Automatic token refresh
+
+#### GPU Resource Management
+- Azure Compute REST API
+- VM provisioning with GPU extensions
+- Real-time status monitoring
+
+#### AI Foundry Integration
+- Azure Machine Learning REST API
+- Model deployment and management
+- Workspace and compute target management
+
+## Error Handling
+
+### Error Codes
+- `0x0001` - Device not found
+- `0x0002` - Connection failed
+- `0x0003` - Authentication failed
+- `0x0004` - Resource unavailable
+- `0x0005` - Invalid parameters
+- `0x0006` - Timeout
+- `0x0007` - Network error
+- `0x0008` - Azure API error
+
+### Exception Handling
+```cpp
+try {
+    device_manager.connectToDevice(device_id);
+} catch (const DeviceException& e) {
+    spdlog::error("Device error: {}", e.what());
+} catch (const NetworkException& e) {
+    spdlog::error("Network error: {}", e.what());
+} catch (const AzureException& e) {
+    spdlog::error("Azure error: {}", e.what());
+}
+```
+
+## Performance Considerations
+
+### Multi-threading
+- Device discovery runs in separate thread
+- Data reception uses thread pool
+- UI updates on main thread
+- Azure operations use async/await pattern
+
+### Memory Management
+- Device connections use smart pointers
+- Data buffers are pre-allocated
+- GPU memory is managed by Azure
+- UI elements are properly disposed
+
+### Network Optimization
+- Connection pooling for multiple devices
+- Data compression for large payloads
+- Heartbeat mechanism for connection monitoring
+- Automatic reconnection on failure
+
+## Security
+
+### Authentication
+- Azure AD integration for cloud resources
+- Device-specific authentication tokens
+- Encrypted communication channels
+- Certificate-based device verification
+
+### Data Protection
+- End-to-end encryption for sensitive data
+- Secure storage of configuration files
+- Access control for device management
+- Audit logging for all operations
+
+## Examples
+
+### Basic Device Management
+```cpp
+DeviceManager manager(8080, 100);
+manager.setDeviceCallback([](const DeviceInfo& device) {
+    std::cout << "Found device: " << device.name << std::endl;
+});
+
+manager.startDiscovery();
+manager.connectToDevice("device-001");
+```
+
+### Azure GPU Provisioning
+```cpp
+AzureConfig config;
+config.subscription_id = "your-subscription-id";
+// ... set other config parameters
+
+AzureIntegration azure(config);
+azure.authenticate();
+azure.provisionGPUResource("gpu-vm-001", "V100", 1, 32);
+```
+
+### UI Integration
+```python
+ui = HolodeckUI()
+ui.start_device_discovery()
+ui.connect_to_azure()
+ui.start_slam_processing()
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Device Discovery Fails**
+   - Check network permissions
+   - Verify firewall settings
+   - Ensure discovery port is available
+
+2. **Azure Authentication Fails**
+   - Verify credentials in configuration
+   - Check Azure AD permissions
+   - Ensure subscription is active
+
+3. **SLAM Processing Errors**
+   - Check camera calibration
+   - Verify sensor data quality
+   - Monitor system resources
+
+4. **UI Performance Issues**
+   - Reduce update rate
+   - Disable unnecessary features
+   - Monitor GPU usage
+
+### Debug Mode
+Enable debug logging by setting environment variable:
+```bash
+export NOWYOUSEE_DEBUG=1
+```
+
+### Log Files
+- Device logs: `/var/log/nowyouseeme/device.log`
+- Azure logs: `/var/log/nowyouseeme/azure.log`
+- SLAM logs: `/var/log/nowyouseeme/slam.log`

+#### CSI Module (`src/ingestion/csi_acquirer.py`)
+```python
+class CSIAcquirer:
+    """WiFi Channel State Information capture"""

+        self.gpu_monitor = GPUMonitor()
+        self.memory_monitor = MemoryMonitor()
+    
+    def optimize_performance(self):
+        """Dynamically adjust settings based on resources"""
+        cpu_usage = self.cpu_monitor.get_usage()
+        gpu_usage = self.gpu_monitor.get_usage()
+        
+        if cpu_usage > 80:
+            self.reduce_processing_quality()

+### Build Issues
+
+#### CMake Errors
+**Symptoms**: Build fails with CMake errors
+
+**Solutions**:
+1. **Install missing dependencies**:
+   ```bash
+   # Ubuntu/Debian
+   sudo apt-get install build-essential cmake libopencv-dev libeigen3-dev
+   
+   # macOS
+   brew install cmake opencv eigen
+   ```
+
+2. **Clear build cache**:
+   ```bash
+   # Clean build directory
+   rm -rf build/
+   mkdir build
+   cd build
+   cmake ..
+   make -j$(nproc)
+   ```
+
+3. **Check CMake version**:
+   ```bash
+   # Update CMake
+   cmake --version
+   # Should be >= 3.16
+   ```
+
+#### Python Build Errors
+**Symptoms**: pip install fails
+
+**Solutions**:
+1. **Update pip and setuptools**:
+   ```bash
+   pip install --upgrade pip setuptools wheel
+   ```
+
+2. **Install build dependencies**:
+   ```bash
+   # Ubuntu/Debian
+   sudo apt-get install python3-dev
+   
+   # macOS
+   xcode-select --install
+   ```
+
+3. **Use virtual environment**:
+   ```bash
+   python -m venv venv
+   source venv/bin/activate
+   pip install -e .
+   ```
