-Discord Voice Translation Bot - Microservices Architecture with GPU-accelerated transcription and multi-language translation
+A comprehensive microservices-based Discord bot that captures voice channel audio, transcribes it using GPU-accelerated Whisper, and provides real-time multi-language translation.
+
+## 🚀 Features
+
+- **Real-time Voice Capture**: Records individual user audio streams from Discord voice channels
+- **GPU-Accelerated Transcription**: Uses faster-whisper with NVIDIA RTX 4000 for lightning-fast speech-to-text
+- **Multi-language Translation**: Supports translation to English, German, Korean, and more
+- **Microservices Architecture**: Scalable, maintainable design with independent services
+- **Web Dashboard**: Real-time monitoring and historical analytics
+- **High Performance**: Optimized for low-latency processing
+
+## 🏗️ Architecture
+
+```
+Discord Voice → [Recorder] → Raw PCM → [Audio Processor] → Optimized WAV
+    ↓
+[Whisper Service] → Transcription → [Translator] → Multi-language
+    ↓
+[Transcriber] → Discord Messages + Database → [Dashboard]
+```
+
+### Services Overview
+
+| Service | Purpose | Technology |
+|---------|---------|------------|
+| **Recorder** | Discord bot + voice capture | Node.js, Discord.js |
+| **Audio Processor** | PCM to WAV conversion | Python, FFmpeg |
+| **Whisper Service** | GPU-accelerated transcription | Python, faster-whisper, CUDA |
+| **Translator** | Multi-language translation | Python, Google/DeepL APIs |
+| **Transcriber** | Workflow orchestration | Node.js, Message queues |
+| **Dashboard** | Web monitoring interface | Node.js, Express, WebSockets |

+cd discord-voice-translator-v2
+```
+
+### 2. Configure Environment
+```bash
+cp .env.example .env
+# Edit .env with your API keys and settings
+```
+
+Required environment variables:
+```bash
+# Discord Bot
+DISCORD_TOKEN=your_discord_bot_token
+CLIENT_ID=your_bot_client_id
+GUILD_ID=your_guild_id
+
+# Database
+POSTGRES_PASSWORD=your_secure_password
+
+# Translation APIs
+GOOGLE_TRANSLATE_API_KEY=your_google_api_key
+DEEPL_API_KEY=your_deepl_api_key
+```
+
+### 3. Start Services
+```bash
+# Start core services
+docker-compose up -d
+
+# Start with admin interfaces
+docker-compose --profile admin up -d
+```
+
+### 4. Verify GPU Support
+```bash
+# Check Whisper service GPU status
+curl http://localhost:8001/health
+```
+
+## 📊 Service Endpoints
+
+| Service | Port | Health Check | Purpose |
+|---------|------|--------------|---------|
+| Whisper Service | 8001 | `/health` | GPU transcription |
+| Translator | 8002 | `/health` | Multi-language translation |
+| Dashboard | 3000 | `/` | Web monitoring |
+| PostgreSQL | 5432 | - | Database |
+| Redis | 6379 | - | Message queue |
+| pgAdmin | 8080 | `/` | Database admin |
+| Redis Commander | 8081 | `/` | Redis admin |
+
+## 🎮 Discord Commands
+
+- `/join` - Join your voice channel and start recording
+- `/leave` - Leave voice channel and stop recording  
+- `/status` - Show current recording status
+
+## 📈 Performance Optimizations
+
+### GPU Configuration
+- **Model**: faster-whisper large-v2 with CUDA
+- **Precision**: float16 for optimal RTX 4000 performance
+- **Memory**: ~2GB VRAM usage for transcription
+- **Speed**: 2-3x real-time transcription
+
+### Audio Processing
+- **Input**: Discord 48kHz stereo PCM
+- **Output**: 16kHz mono WAV (optimized for Whisper)
+- **Conversion**: FFmpeg with fallback to Python/scipy
+- **Cleanup**: Automatic removal of processed PCM files
+
+## 🗄️ Database Schema
+
+- **connections**: Voice channel session tracking
+- **recordings**: Individual user audio recordings
+- **transcriptions**: Speech-to-text results with confidence scores
+- **translations**: Multi-language translation results
+- **processing_metrics**: Performance monitoring
+- **user_activity**: Aggregated usage statistics
+
+## 🔧 Development
+
+### Local Development
+```bash
+# Individual service development
+cd services/recorder
+npm install
+npm run dev
+
+# Audio processor
+cd services/audio-processor  
+pip install -r requirements.txt
+python src/processor.py
+```
+
+### Testing GPU Support
+```bash
+# Verify NVIDIA Docker runtime
+docker run --rm --gpus all nvidia/cuda:11.8-base-ubuntu22.04 nvidia-smi
+
+# Test Whisper service
+docker-compose exec whisper-service python -c "import torch; print(torch.cuda.is_available())"
+```
+
+## 📝 Logging
+
+- **Structured Logging**: JSON format for all services
+- **Log Levels**: Configurable via `LOG_LEVEL` environment variable
+- **Centralized**: All logs stored in `/data/logs/`
+- **Monitoring**: Real-time log viewing via dashboard
+
+## 🔐 Security
+
+- **Environment Variables**: Secure credential management
+- **Database**: PostgreSQL with connection encryption
+- **Network**: Internal Docker network isolation
+- **API Keys**: Separate service credentials
+
+## 🚀 Deployment
+
+### Unraid Setup
+1. Install Community Applications plugin
+2. Add Docker Compose plugin
+3. Configure GPU passthrough
+4. Import docker-compose.yml
+
+### Production Considerations
+- **SSL**: Configure Nginx reverse proxy with SSL certificates
+- **Backup**: Regular database and configuration backups
+- **Monitoring**: Set up health check alerts
+- **Scaling**: Horizontal scaling for high-traffic Discord servers
+
+## 🛠️ Troubleshooting
+
+### Common Issues
+
+**GPU Not Detected**
+```bash
+# Check NVIDIA drivers
+nvidia-smi
+
+# Verify Docker GPU support
+docker run --rm --gpus all nvidia/cuda:11.8-base nvidia-smi
+```
+
+**Service Won't Start**
+```bash
+# Check logs
+docker-compose logs [service-name]
+
+# Verify environment variables
+docker-compose config
+```
+
+**Audio Processing Slow**
+- Verify GPU acceleration is working
+- Check available VRAM
+- Monitor CPU usage during conversion
