+
+## Configuration
+
+Edit `config.py` to customize:
+
+```python
+# Model size (tiny, base, small, medium, large)
+DEFAULT_MODEL = "medium"
+
+# Language code
+LANGUAGE_CODE = "fa"  # Farsi
+
+# Supported formats
+SUPPORTED_AUDIO_FORMATS = {".mp3", ".wav", ".m4a", ".flac", ".ogg", ...}
+SUPPORTED_VIDEO_FORMATS = {".mp4", ".mkv", ".mov", ".webm", ".avi", ...}
 ```
 
 ## Model Information
 
-This application uses OpenAI's Whisper model optimized for Farsi:
-- **Model**: medium or large (configurable)
-- **Accuracy**: Optimized for Persian language
-- **Processing**: Local processing (no cloud required)
+### Available Models
+
+| Model | Size | Speed | Accuracy | VRAM |
+|-------|------|-------|----------|------|
+| tiny | 39M | ~10x | Good | ~1GB |
+| base | 74M | ~7x | Very Good | ~1GB |
+| small | 244M | ~4x | Excellent | ~2GB |
+| medium | 769M | ~2x | Excellent | ~5GB |
+| large | 1550M | 1x | Best | ~10GB |
+
+**Default**: `medium` (recommended for Farsi)
+
+### Performance Notes
+
+- Larger models provide better accuracy but require more VRAM
+- GPU (CUDA) dramatically speeds up transcription (8-10x faster)
+- First run downloads the model (~500MB-3GB depending on model size)
+- Subsequent runs use cached model files

+## Troubleshooting
+
+### Issue: "ffmpeg not found"
+**Solution**: Install ffmpeg using your package manager (see Installation section)
+
+### Issue: "CUDA out of memory"
+**Solution**: Use a smaller model or reduce audio processing in chunks
+
+### Issue: "Model download fails"
+**Solution**: Check internet connection, try again. Models are cached in `~/.cache/whisper/`
+
+### Issue: Slow transcription
+**Solution**: Ensure CUDA is detected (`nvidia-smi`), or upgrade to a smaller/faster model
+
+## Advanced Usage
+
+### Custom Model Selection
+
+Update `config.py`:
+```python
+DEFAULT_MODEL = "large"  # For maximum accuracy
+# or
+DEFAULT_MODEL = "tiny"   # For fastest processing
+```
+
+### Batch Processing (Future)
+
+Script to process multiple files:
+```python
+from farsi_transcriber.models.whisper_transcriber import FarsiTranscriber
+
+transcriber = FarsiTranscriber(model_name="medium")
+for audio_file in audio_files:
+    result = transcriber.transcribe(audio_file)
+    # Process results
+```
+
+## Performance Tips
+
+1. **Use GPU** - Ensure NVIDIA CUDA is properly installed
+2. **Choose appropriate model** - Balance speed vs accuracy
+3. **Close other applications** - Free up RAM/VRAM
+4. **Use SSD** - Faster model loading and temporary file I/O
+5. **Local processing** - All processing happens locally, no cloud uploads
+
