 ## 🔍 AI Matching Criteria
 
-The engine uses three primary criteria for matching:
+The engine uses multiple criteria for matching:
 
 1. **Amount Similarity** - Compares receipt and transaction amounts (5% tolerance)
 2. **Date Proximity** - Checks date closeness (7-day tolerance)
-3. **Vendor Matching** - AI-powered vendor name comparison
+3. **Vendor Matching** - AI-powered vendor name comparison using Groq LLM
+4. **Rule-based Auto-approval** - Automatic approval for exact matches and high-confidence matches

 ## 🚀 Production Deployment
 
 For production deployment:
-- Replace in-memory storage with a database
-- Configure proper authentication
-- Set up monitoring and logging
-- Use environment variables for configuration
+- Replace in-memory storage with a database (PostgreSQL recommended)
+- Configure proper authentication and authorization
+- Set up monitoring and logging (ELK stack recommended)
+- Use environment variables for all configuration
 - Implement proper error handling and retries
+- Set up rate limiting and API quotas
+- Configure CORS for frontend integration
+- Use HTTPS in production

+## 🔧 Troubleshooting
+
+### Common Issues
+
+1. **API Key Error**: Ensure `GROQ_API_KEY` is set in your `.env` file
+2. **Port Already in Use**: Kill existing process with `pkill -f "python main.py"`
+3. **Import Errors**: Install dependencies with `pip install -r requirements.txt`
+4. **Rate Limiting**: The system includes built-in rate limiting to prevent API quota exhaustion
