+# Network Mode Selection Guide
+
+## New Features
+
+### 1. **Network Mode Dropdown** (PC Only)
+
+On PC builds, you'll now see a dropdown in the main menu:
+- **ENet (PC/LAN)**: Traditional IP-based networking for PC players
+- **WebRTC (Browser/Web)**: Web-compatible networking using room codes
+
+The dropdown is automatically hidden on web builds (WebRTC is auto-selected).
+
+### 2. **--webrtc Command Line Flag**
+
+Force WebRTC mode on PC builds:
+
+```bash
+# Start as host with WebRTC
+godot --path . -- --host --webrtc
+
+# Join with WebRTC
+godot --path . -- --join --webrtc --address=ABC123
+
+# Example with room code
+godot --path . -- --join --webrtc --address=XYZ789
+```
+
+## Usage Examples
+
+### PC to PC (Same LAN) - ENet Mode
+
+**PC 1 (Host):**
+1. Select "ENet (PC/LAN)" in dropdown
+2. Click "Host Game"
+3. Note your IP (e.g., 192.168.1.100)
+
+**PC 2 (Join):**
+1. Select "ENet (PC/LAN)" in dropdown
+2. Enter host IP in "Server Address"
+3. Click "Join Game"
+
+### PC to PC (Internet) - WebRTC Mode
+
+**PC 1 (Host):**
+1. Select "WebRTC (Browser/Web)" in dropdown
+2. Click "Host Game"
+3. Share the 6-character room code (e.g., "ABC123")
+
+**PC 2 (Join):**
+1. Select "WebRTC (Browser/Web)" in dropdown
+2. Enter room code in "Server Address"
+3. Click "Join Game"
+
+### PC to Browser - WebRTC Mode
+
+**PC (Host):**
+1. Select "WebRTC (Browser/Web)" in dropdown
+2. Click "Host Game"
+3. Share room code
+
+**Browser (Join):**
+1. Enter room code (WebRTC auto-detected)
+2. Click "Join Game"
+
+### Browser to Browser - WebRTC Mode
+
+**Browser 1 (Host):**
+1. Click "Host Game"
+2. Share room code
+
+**Browser 2 (Join):**
+1. Enter room code
+2. Click "Join Game"
+
+## Command Line Examples
+
+### Test with WebRTC
+
+```bash
+# Terminal 1 - Host with WebRTC
+godot --path . -- --host --webrtc
+
+# Terminal 2 - Join with WebRTC (room code from Terminal 1)
+godot --path . -- --join --webrtc --address=ABC123
+```
+
+### Test with ENet (Default)
+
+```bash
+# Terminal 1 - Host
+godot --path . -- --host
+
+# Terminal 2 - Join
+godot --path . -- --join --address=127.0.0.1
+```
+
+### Test with Multiple Local Players
+
+```bash
+# Host with 2 local players using WebRTC
+godot --path . -- --host --webrtc --players=2
+
+# Join with 2 local players
+godot --path . -- --join --webrtc --address=ABC123 --players=2
+```
+
+## When to Use Each Mode
+
+### Use **ENet** When:
+- Playing on same LAN (local network)
+- Both players are on PC (Windows/Linux/Mac)
+- You want lower latency
+- You have direct network access
+
+### Use **WebRTC** When:
+- Playing over the internet (through NATs/firewalls)
+- Playing with browser users
+- Playing on mobile browsers
+- You want easy room code sharing (no IP addresses)
+
+## Technical Details
+
+### ENet
+- Protocol: UDP
+- Connection: Direct IP:Port
+- Latency: Lower (direct connection)
+- NAT Traversal: Requires port forwarding
+- Compatibility: PC only
+
+### WebRTC
+- Protocol: UDP/DTLS via WebRTC
+- Connection: Room codes via signaling server
+- Latency: Slightly higher (STUN/relay)
+- NAT Traversal: Automatic (STUN/TURN)
+- Compatibility: PC, Browser, Mobile
+
+### Your Servers
+- **Matchbox Signaling**: `ws://ruinborn.thefirstboss.com:3536`
+- **STUN Server**: `stun:ruinborn.thefirstboss.com:3578`
+
+## Troubleshooting
+
+**Dropdown not visible:**
+- This is normal on web builds (WebRTC auto-selected)
+
+**Can't connect in ENet mode:**
+- Check firewall (port 21212)
+- Verify IP address is correct
+- Try WebRTC mode instead
+
+**Can't connect in WebRTC mode:**
+- Verify room code matches exactly
+- Check matchbox server is running
+- Try ENet mode for LAN play
+
+**Room code not showing:**
+- Only shown in console when hosting with WebRTC
+- Will be displayed in UI in future updates
+
+## Future Improvements
+
+- [ ] Display room code in UI (not just console)
+- [ ] Copy room code to clipboard button
+- [ ] Lobby browser (see active rooms)
+- [ ] Remember last used network mode
+- [ ] Auto-detect best mode for connection
