+## 🌐 Web Admin Interface
+
+C-Relay includes a **built-in web-based administration interface** accessible at `http://localhost:8888/api/`. The interface provides:
+
+- **Real-time Configuration Management**: View and edit all relay settings through a web UI
+- **Database Statistics Dashboard**: Monitor event counts, storage usage, and performance metrics
+- **Auth Rules Management**: Configure whitelist/blacklist rules for pubkeys
+- **NIP-42 Authentication**: Secure access using your Nostr identity
+- **Event-Based Updates**: All changes are applied as cryptographically signed Nostr events
+
+The web interface serves embedded static files with no external dependencies and includes proper CORS headers for browser compatibility.
+
 ## 🔧 Administrator API
 
 C-Relay uses an innovative **event-based administration system** where all configuration and management commands are sent as signed Nostr events using the admin private key generated during first startup. All admin commands use **NIP-44 encrypted command arrays** for security and compatibility.
