 ## Features
 
+### HTTP Debugging
 - **Network Interception** - Automatically captures all `fetch()` and `XMLHttpRequest` calls
-- **Draggable Overlay** - Floating button that can be positioned anywhere on screen
 - **Request Details** - View headers, body, response, timing, and status codes
 - **cURL Export** - Copy requests as cURL commands
 - **Advanced Filtering** - Filter by status code (2xx, 3xx, 4xx, 5xx), search by URL/method/body
 - **Export Logs** - Export to HAR, Postman Collection, or JSON formats
 - **Request Replay** - Re-execute captured requests with optional modifications
-- **Dark/Light Theme** - Toggle between themes
 - **Slow Request Detection** - Visual indicator for requests exceeding threshold
 - **Sensitive Data Redaction** - Detect and mask sensitive headers and body fields
+
+### WebSocket Debugging
+- **WebSocket Interception** - Automatically captures all WebSocket connections
+- **Connection Monitoring** - Track connection state (connecting, open, closing, closed)
+- **Message Logging** - View sent and received messages with timestamps
+- **Message Filtering** - Filter by direction (sent/received) or search by content
+- **Binary Support** - Handles text and binary message types
+- **Connection Metrics** - Track message counts, bytes transferred, and connection duration
+- **Live Indicators** - Visual indicators for active connections
+
+### General
+- **Unified Interface** - Tabbed modal with HTTP and WebSocket views
+- **Draggable Overlay** - Floating button that can be positioned anywhere on screen
+- **Dark/Light Theme** - Toggle between themes
 - **Individual Log Deletion** - Remove specific entries without clearing all logs
 - **Device Shake Support** - Shake to show/hide the debugger
 - **TypeScript Support** - Full type definitions included

 ## Production Safety
@@ -383,9 +535,35 @@ Make sure `setupInterceptor()` is called before any network requests:
 ```tsx
 useEffect(() => {
   networkLogger.setupInterceptor();
+  webSocketLogger.setupInterceptor();
 }, []); // Empty dependency array - runs once on mount
 ```
 
+### WebSocket connections not appearing
+
+Ensure you have:
+1. Called `webSocketLogger.setupInterceptor()` before any WebSocket connections
+2. Set `enableWebSocket={true}` on the NetworkLoggerOverlay
+3. Passed the `webSocketLogger` prop
+
+```tsx
+<NetworkLoggerOverlay
+  networkLogger={networkLogger}
+  webSocketLogger={webSocketLogger}
+  enableWebSocket={true}  // Required to show WebSocket tab
+  draggable={true}
+/>
+```
+
+### Setup error messages
+
+The debugger will throw helpful error messages if interceptors aren't initialized:
+
+- **HTTP**: If `networkLogger.setupInterceptor()` wasn't called before rendering
+- **WebSocket**: If `enableWebSocket={true}` but `webSocketLogger.setupInterceptor()` wasn't called
+
+These errors include code examples to help you fix the issue quickly.
