-## 🏗️ Architecture
-
-### Services
-- **Backend** (FastAPI + MTGJSON integration)
-- **PostgreSQL** (main + mtgdata - separate database for MTG data)
-- **Redis** (caching)
-- **Refresh** (weekly MTGJSON sync job)
 
 ### Data Flow
-```
-MTGJSON API (https://mtgjson.com/api/v5)
-    ↓
-Download AllPrintings.json.gz (500MB+)
-    ↓
-Unpack & Validate
-    ↓
-Upsert to PostgreSQL (ON CONFLICT DO UPDATE)
-    ↓
-Health Check verifies data exists
+1. Backend connects to PostgreSQL (both instances) and Redis on startup
+2. Checks `mtg_refresh_log` in `mtgdata` database for existing data
+3. If no data exists, downloads MTGJSON files from `https://mtgjson.com/api/v5/`
+4. Upserts data into `mtgdata` tables (`mtg_sets`, `mtg_cards`, etc.)
+5. Data available via REST endpoints
+
+### Key Database Connections
+- **Primary DB**: `postgresql+asyncpg://mtgonline_user:mtgonline_password@postgres:5432/mtgonline`
+- **MTG DB**: `postgresql+asyncpg://mtgonline_user:mtgonline_password@mtgdata:5432/mtgdata`
+- **Redis**: `redis://redis:6379`

-## 🐛 Known Issues & Fixes
-
-### Issue 1: MTGJSON URL Scheme Change
-**Problem**: MTGJSON changed from `.json` to `.json.gz` URLs
-
-**Fix**: Updated URLs in `mtgjson_manager.py`:
-```python
-MTGJSON_BASE_URL = "https://mtgjson.com/api/v5"
-REQUIRED_FILES = {
-    "AllPrintings.json.gz": MTGJSON_BASE_URL + "/AllPrintings.json.gz",
-    # ...
-}
-```
-
-### Issue 2: Pre-uncompressed Files
-**Problem**: Some `.gz` files are actually plain JSON
-
-**Fix**: Check magic bytes before decompression:
-```python
-with open(gz_file, 'rb') as f:
-    magic = f.read(2)
-if magic == b'\x1f\x8b':  # gzip
-    # decompress
-else:
-    # just rename
-```
-
-### Issue 3: Large File Download Times
-**Solution**: 
-- Timeout set to 60 minutes
-- Start period set to 10 minutes
-- Files cached in volume

----
-
-## 🛠️ Manual Operations
-
-### Refresh Data
+### Start Services
 ```bash
 cd /home/wall-o/projects/mtgonline
-bash backend/scripts/refresh_mtg.py
+docker compose -f docker-compose.dev.yml up -d
 ```
 
-### Run Sanity Check
+### Check Services
 ```bash
-python backend/scripts/sanity_check_mtgjson.py
+docker compose -f docker-compose.dev.yml ps
+docker compose -f docker-compose.dev.yml logs -f backend
 ```
 
-### Verify Data
+### Stop Services
 ```bash
-docker exec -it mtgonline_postgres_mtgdata psql -U postgres -c "SELECT count(*) FROM mtg_cards;"
+docker compose -f docker-compose.dev.yml down
 ```
 
----
+### Full Cleanup
+```bash
+# Stop and remove all containers
+docker compose -f docker-compose.dev.yml down
 
-## 📝 State Tracking
+# Remove images
+docker images rm mtgonline-backend:latest postgres:14-alpine redis:7-alpine
+
+# Clear build cache and prune
+docker builder prune -af
+docker system prune -af --volumes
+```
+
+## Testing
+
+### Run Tests
+```bash
+cd /home/wall-o/projects/mtgonline/backend
+docker exec -it <backend_container_id> pytest
+# OR
+cd /home/wall-o/projects/mtgonline/backend
+pytest
+```
+
+### Database Verification
+```bash
+# Check MTG data tables
+docker exec <mtgdata_container_id> psql -U mtgonline_user mtgdata -c "\dt"
+
+# Check refresh log
+docker exec <mtgdata_container_id> psql -U mtgonline_user mtgdata -c "SELECT * FROM mtg_refresh_log ORDER BY refresh_time DESC LIMIT 5;"
+```
+
+## Troubleshooting
+
+### Backend can't connect to databases
+- Verify all services are running: `docker compose -f docker-compose.dev.yml ps`
+- Check logs: `docker compose -f docker-compose.dev.yml logs backend`
+- Ensure environment variables match docker-compose.dev.yml
+
+### MTGJSON download fails
+- Check network connectivity to mtgjson.com
+- Verify DATA_DIR has write permissions
+- Check disk space: `df -h`
+- Manual download: `python scripts/download_mtgjson.py`
+
+### Database tables missing
+- Run initialization: `docker exec -i <mtgdata_container_id> psql -U mtgonline_user mtgdata < /path/to/scripts/init-mtgdata.sql`
+- Check tables: `docker exec <mtgdata_container_id> psql -U mtgonline_user mtgdata -c "\dt"`
+
+### CORS errors
+- Check CORS_ORIGINS setting in app/core/settings.py
+- Ensure frontend URL matches allowed origins
+
+## Next Phase: Backend Expansion for Frontend Support
+
+**Primary Focus**: Expand the PostgreSQL database schema and API endpoints to support frontend deckbuilding and gameplay features on a per-user basis.
+
+### Database Schema Expansion
+- Per-user deck storage (decks, folders, custom card sets)
+- Game state persistence (saved games, match history, game logs)
+- User card collection tracking (owned cards, favorites)
+- Game room state management (active games, waiting lists)
+- Tournament and custom rule support
+
+### API Endpoints to Implement
+- Deck CRUD with user ownership and sharing
+- Game room creation, joining, and state management
+- Real-time WebSocket endpoints for multiplayer gameplay
+- Card collection APIs (search, filter, organize)
+- Game history and replay APIs
+- Admin tools for game monitoring and moderation
+
+### Frontend Features to Support (from ROADMAP.md Phase 2)
+- **Deck Builder**: Card search with filters (name, color, type, set), drag-and-drop editor, import/export formats
+- **Game Interface**: Game board visualization, player zones (hand, library, graveyard, exile, command), real-time updates
+- **Chat System**: Room chat, game chat, player list, moderator tools
+- **Admin Dashboard**: User management, ban/unban controls, game logs, system statistics
+
+### Integration Requirements (from ROADMAP.md Phase 3)
+- WebSocket client with reconnection logic
+- Card database caching and search functionality
+- Game logic implementation (turn-based state, mana tracking, stack resolution)
+- Performance optimization (virtual scrolling, memoization, code splitting)
+
+### Deployment & Production (from ROADMAP.md Phase 4)
+- Docker Compose for development and production
+- CI/CD pipeline with GitHub Actions
+- Security hardening (rate limiting, input validation, HTTPS)
+- Monitoring and alerting (structured logging, error tracking)
+
+See **ROADMAP.md** for complete feature specifications and timeline.
