-Telegram miniapp для поиска музыки на YouTube и конвертации в MP3.
+Telegram miniapp для поиска и скачивания музыки (в разработке).
 
-## Возможности
+## ⚠️ Current Status: UNDER DEVELOPMENT
 
-- 🔍 Поиск видео на YouTube
+**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

 ### Next Steps for Deployment
-- [ ] Install FFmpeg on target server
+- [x] Install FFmpeg on target server  
-- [ ] Set up environment variables
+- [x] Set up environment variables
-- [ ] Configure Telegram bot with BotFather
+- [x] Configure Telegram bot with BotFather
-- [ ] Deploy to hosting platform (Heroku/VPS)
+- [x] Deploy to hosting platform (Docker with Traefik SSL)
+
+## 2025-08-26
+
+### TypeScript Migration
+- [x] Migrated entire project from JavaScript to TypeScript
+- [x] Added type definitions for all dependencies
+- [x] Created separate TypeScript configs for backend/frontend
+- [x] Updated build process and package.json scripts
+- [x] All files converted: server.ts, bot.ts, database.ts, soundcloud.ts, script.ts
+
+### Docker & Production Setup  
+- [x] Complete Docker setup with multi-stage builds
+- [x] Traefik reverse proxy with automatic SSL (Let's Encrypt)
+- [x] GitHub Actions CI/CD with security scanning
+- [x] Production deployment configuration
+
+## 2025-08-27
+
+### Critical Issues Discovered
+- [x] YouTube integration completely blocked by bot detection
+- [x] Attempted multiple YouTube packages (play-dl, ytdl-core, youtube-dl-exec)
+- [x] All anonymous methods return 403 errors from YouTube
+- [x] SoundCloud integration attempted as replacement
+
+### SoundCloud Integration Failure
+- [x] Installed soundcloud-downloader package
+- [x] Created SoundCloudService class with proper error handling
+- [x] **CRITICAL BUG FOUND**: Frontend sends YouTube video IDs, backend expects SoundCloud IDs
+- [x] This architectural mismatch breaks the entire conversion flow
+
+### Current Status: BROKEN
+- ❌ **Music search**: No working backend service
+- ❌ **MP3 conversion**: Depends on working search
+- ❌ **Download functionality**: Cannot find tracks
+- ✅ **Infrastructure**: Telegram bot, database, Docker all working
+- ✅ **Frontend UI**: Search interface functional
+- ✅ **TypeScript**: Full type safety implemented
+
+### Alternative Sources Analysis
+- [x] Evaluated Archive.org, Jamendo, Bandcamp, Spotify
+- [x] Archive.org identified as most promising (largest free collection)
+- [ ] **NEXT**: Implement Archive.org integration
+- [ ] **NEXT**: Fix frontend-backend service mismatch
