+## 🔧 Backend API
+
+### REST Endpoints
+
+**POST /api/login**
+- Login and create player
+- Body: `{"username": "name", "color": "#FF6B6B"}`
+- Returns: Player data, session ID, game status
+
+**GET /api/game/state**
+- Get full game state (players, monsters, structures, resources)
+- Returns: Complete game world data
+
+**POST /api/player/{player_id}/move**
+- Move player
+- Body: `{"dx": 5, "dy": 0}`
+- Returns: New position, action points
+
+**POST /api/player/{player_id}/action**
+- Perform action (attack, gather, build)
+- Body: `{"action_type": "attack", "target_id": "monster_123"}`
+- Returns: Action result
+
+**POST /api/game/start**
+- Start/restart the game round
+- Returns: Game status
+
+**GET /api/health**
+- Server health check
+- Returns: `{"status": "ok"}`
+
+### WebSocket Connection
+
+**WS /ws/{player_id}**
+- Real-time game updates (10 updates/second)
+- Receive: Player positions, monster data, boss status, timer
+- Automatic game tick updates
+
+## 📊 Game Configuration
+
+Edit constants in `backend.py` to customize:
+
+```python
+GAME_DURATION = 30 * 60              # 30 minutes
+GRID_SIZE = 500                      # 500x500 tile map
+ACTION_POINTS_MAX = 20               # Starting action points
+ACTION_POINTS_REGEN_INTERVAL = 60    # 1 minute regeneration
+MONSTER_SPAWN_RATE = 0.1             # Spawn rate per tick
+MAX_MONSTERS = 50                    # Max monsters on map
+BOSS_HEALTH_BASE = 1000              # Boss starting health
+MIN_LEVEL_FOR_BOSS = 10              # Minimum level to spawn boss
+```
+
+## 🎨 Customization
+
+### Colors
+Edit the color array in `index.html` to add/change player colors:
+```javascript
+const colors = ['#FF6B6B', '#4ECDC4', '#45B7D1', ...];
+```
+
+### Game Duration
+Change `GAME_DURATION` in `backend.py`:
+```python
+GAME_DURATION = 15 * 60  # 15 minutes instead of 30
+```
+
+### Difficulty
+Adjust these values in `backend.py`:
+- Increase `BOSS_HEALTH_BASE` for harder boss
+- Increase `MONSTER_SPAWN_RATE` for more monsters
+- Change `MIN_LEVEL_FOR_BOSS` for earlier/later boss appearance
+
+## 🐛 Troubleshooting
+
+### Port 8000 Already in Use
+```bash
+# Find process using port 8000 and kill it
+lsof -i :8000
+kill -9 <PID>
+
+# Or use different port
+python -m uvicorn backend:app --host 0.0.0.0 --port 8001
+```
+
+### Browser Won't Load Game
+- Make sure backend is running: http://localhost:8000/docs
+- Try refreshing the page
+- Clear browser cache
+- Try a different browser
+
+### Game Lags
+- Reduce player count (have fewer people logged in)
+- Lower monitor refresh rate
+- Close other browser tabs
+
+### Action Points Not Regenerating
+- Game must be running (wait for "Game Started" message)
+- Action points regenerate every 60 seconds
+- Farm structures nearby increase regeneration
+
+## 📝 Technical Stack
+
+- **Backend**: FastAPI + Uvicorn + WebSockets
+- **Frontend**: HTML5 + Three.js (WebGL)
+- **Real-time**: WebSocket protocol for live updates
+- **Language**: Python 3.8+, JavaScript
+
+## 🚀 Future Features
+
+- Persistent database for leaderboards
+- Player guilds/teams
+- More structure types
+- Trading between players
+- PvP combat zones
+- Quests and achievements
+- Mobile app version
+- Seasonal resets with new content
+- Boss tier progression
+- Special events and limited-time challenges
+
+## 📞 Support
+
+If you encounter issues:
+1. Check error messages in browser console (F12)
+2. Check terminal output for server errors
+3. Verify all dependencies installed: `pip list`
+4. Try restarting the server
+
+## 🎉 Enjoy!
+
+You now have a working multiplayer RPG! Invite friends, explore, and defeat the boss together!
+
+Good luck, adventurer! 🗡️⚔️🛡️

+   
+   Terminal 2:
+   • Open file:///Users/luka/dev/me/web-adventure/index.html
+     in your web browser
+
+3. CHECK: Run verification script
+   ================================
+   $ python verify.py
+   
+   Verifies all components are set up correctly
