+# Multi-Agent YouTube Processing Workflow
+
+A comprehensive multi-agent workflow built with CrewAI that processes YouTube videos through transcription, translation, summarization, and local output.
+
+## 🎯 Overview

+
+## 🔧 Customization
+
+### Adding Custom Prompts
+
+You can customize summarization prompts for different use cases:
+
+```python
+# Educational summary
+educational_prompt = "Summarize in 5 bullet points for students to revise quickly"
+
+# Business summary  
+business_prompt = "Create a 3-point executive summary highlighting key business insights"
+
+# Creative summary
+creative_prompt = "Rewrite as an engaging story with dialogue and vivid descriptions"
+```
+
+### Modifying Agent Behavior
+
+Each agent can be customized in its respective file:
+
+- **Transcriber**: Modify `YouTubeTranscriber` class in `utils/speech_processing.py`
+- **Translator**: Update translation logic in `agents/translator_agent.py`
+- **Summarizer**: Customize summarization prompts in `agents/summarizer_agent.py`
+- **Publisher**: Modify API integration in `agents/publisher_agent.py`
+
+### Adding New Languages
+
+The translation system supports 100+ languages. Simply specify the language name in your target language:
+
+```python
+supported_languages = [
+    "Spanish", "French", "German", "Italian", "Portuguese",
+    "Chinese", "Japanese", "Korean", "Arabic", "Russian", 
+    "Dutch", "Swedish", "Norwegian", "Danish", "Finnish"
+]
+```
+
+## 🐛 Troubleshooting
+
+### Common Issues
+
+#### FFmpeg Not Found
+```
+Error: ffmpeg not found
+```
+**Solution**: Install FFmpeg and ensure it's in your system PATH.
+
+#### Whisper Model Download Issues
+```
+Error downloading Whisper model
+```
+**Solution**: Check internet connection and ensure sufficient disk space (~1GB per model).
+
+#### API Key Errors
+```
+Error: PERPLEXITY_API_KEY not found
+```
+**Solution**: Verify your `.env` file contains valid API keys.
+
+#### YouTube Access Issues
+```
+Error extracting audio from YouTube video
+```
+**Solution**: 
+- Ensure the video is public and accessible
+- Check if the video has age restrictions
+- Verify the URL format is correct
+
+### Debug Mode
+
+Enable debug logging for detailed error information:
+
+```python
+import logging
+logging.basicConfig(level=logging.DEBUG)
+```
+
+## 📊 Performance Tips
+
+1. **Model Selection**: Use smaller Whisper models (`tiny`, `base`) for faster processing
+2. **Batch Processing**: Process multiple videos using the API for better throughput
+3. **Caching**: Implement caching for repeated transcriptions of the same video
+4. **Async Processing**: Use async/await patterns for large-scale deployments
+
+## 🧪 Testing

+Run the test suite:
+
+```bash
+# Test individual components
+python -m pytest tests/
+
+# Test complete workflow
+python test_workflow.py
