+### WebRTC ICE Servers Configuration
+
+The Ring Network uses WebRTC for peer-to-peer connections. You can configure custom ICE servers (STUN/TURN) for better connectivity:
+
+#### Using Command Line
+```bash
+# With custom STUN servers
+node node.js --ice-servers '[{"urls":"stun:your-stun-server.com:19302"}]'
+
+# With TURN server for NAT traversal
+node node.js --ice-servers '[{"urls":"stun:stun.l.google.com:19302"},{"urls":"turn:your-turn-server.com:3478","username":"user","credential":"pass"}]'
+```
+
+#### Using Configuration Files
+```bash
+# Load from config file
+node node.js --config config/ice-servers-with-turn.json
+
+# For Oracle nodes
+node oracle.js --config config/ice-servers-public-turn.json
+```
+
+#### Available Configuration Examples
+- `config/ice-servers-default.json` - Default Google STUN servers
+- `config/ice-servers-with-turn.json` - Template with TURN server
+- `config/ice-servers-public-turn.json` - Public TURN servers for testing
+
+#### ICE Server Configuration Format
+```json
+{
+  "iceServers": [
+    {
+      "urls": "stun:stun.l.google.com:19302"
+    },
+    {
+      "urls": "turn:turnserver.example.com:3478",
+      "username": "your_username",
+      "credential": "your_password"
+    }
