-# MTG Online Backend - Project State
-
-## Project Overview
-A Python FastAPI backend service for MTG Online (Magic: The Gathering) that integrates with MTGJSON data and provides APIs for deck management, game rooms, and card data.
-
-## Current Status: Ready for Deployment
-
-### Completed Steps
-1. ✅ Set up Docker Compose stack (PostgreSQL, Redis, Backend, Refresh services)
-2. ✅ Clean up corrupted MTGJSON data files
-3. ✅ Downloaded fresh MTGJSON data from API
-4. ✅ Simplified MTGJSON data management service
-5. ✅ Updated database schema to support all JSON data
-6. ✅ Fixed directory naming issues
-7. ✅ Rebuilt and redeployed backend
-
-### Next Steps
-- Verify backend health and database connectivity
-- Test the refresh cycle
-- Confirm all MTGJSON data is properly stored
-
