+# PostgreSQL Migration Completed
+
+## Changes Made
+- **Docker Compose**: Added PostgreSQL 15 service with persistent data volume
+- **Database Configuration**: Migrated from SQLite3 to PostgreSQL using pg library
+- **Package Dependencies**: Updated package.json (removed sqlite3, added pg and @types/pg)
+- **Database Class**: Converted all methods to use PostgreSQL syntax and async/await pattern
+
+## Key Configuration
+- Database URL: `postgresql://quixotic:quixotic123@postgres:5432/quixotic`
+- Container: `quixotic-postgres` with health checks
+- Volume: `postgres-data` for data persistence
+- Environment variables: POSTGRES_DB, POSTGRES_USER, POSTGRES_PASSWORD
+
+## Database Schema Changes
+- INTEGER PRIMARY KEY → SERIAL PRIMARY KEY
+- BIGINT for telegram_id (better for large Telegram IDs)
+- TIMESTAMP instead of DATETIME
+- PostgreSQL-style REFERENCES syntax for foreign keys
+- ON CONFLICT DO UPDATE for upsert operations
+
+## Status
+✅ Migration completed successfully
+✅ Application starts without database errors
+✅ All dependencies installed
+✅ Docker containers running properly

 # 🎵 Quixotic - Music Search Telegram MiniApp
 
-Telegram miniapp для поиска и скачивания музыки (в разработке).
+Telegram miniapp для поиска и скачивания музыки
-
-## ⚠️ Current Status: UNDER DEVELOPMENT
-
-**The app is currently non-functional** due to the following issues:
-
-- ❌ **YouTube integration abandoned** - Bot detection blocks all anonymous access
-- ❌ **SoundCloud integration failed** - API restrictions and ID mismatch between frontend/backend  
-- 🔄 **TypeScript migration completed** - All code converted from JavaScript to TypeScript
-- 🔄 **Alternative sources being evaluated** - Archive.org, Jamendo, Bandcamp under consideration
-
-### What Works:
-- ✅ Telegram Bot setup and Web App integration
-- ✅ Frontend interface (search/UI)  
-- ✅ SQLite database functionality
-- ✅ Docker deployment setup with Traefik SSL
-- ✅ Full TypeScript support with proper typing
-
-### What's Broken:
-- ❌ Music search (no working backend service)
-- ❌ MP3 conversion (depends on working search)
-- ❌ Download functionality
-
-## Планируемые возможности
-
-- 🔍 Поиск музыки (источник определяется)
-- 🎵 Конвертация в MP3 с помощью FFmpeg  
-- 📱 Telegram Web App интерфейс (✅ готов)
-- 💾 SQLite база данных (✅ готова)
-- 📊 История поиска (✅ готова)
-- 🤖 Telegram Bot интеграция (✅ готова)
