-- `get_integration_status()` - Get current status and stats
-- `configure_optimizer(**kwargs)` - Configure optimization parameters
-- `benchmark_optimization(...)` - Run performance benchmarks
+### Compatibility
 
-### Classes
+- **MLX Version**: Requires MLX >= 0.26.0
+- **MLX-LM Version**: Requires MLX-LM >= 0.25.0
+- **Python Version**: Python 3.8+
+- **Platform**: macOS with Apple Silicon only
 
-- `MetalKernelOptimizer` - Core optimization engine
-- `AttentionConfig` - Attention pattern configuration
-- `MLXLMIntegration` - Integration management

+### Known Limitations
 
-## 🤝 Contributing
+1. **Metal Kernel Scope**: Only optimizes attention computation, not full model
+2. **Sequence Length**: Maximum efficient sequence length is 4096 tokens
+3. **Batch Size**: Optimizations most effective for batch sizes 1-4
+4. **Running Directory**: Must run from integration/ directory for imports to work
 
-1. Test on different model architectures
-2. Optimize for specific sequence length ranges
-3. Add support for new attention patterns
-4. Improve Metal kernel performance
-5. Add more comprehensive benchmarks

+## 🤝 Usage Best Practices
+
+### Do's
+
+✅ Run from the integration/ directory  
+✅ Install requirements with `pip install -r requirements.txt`  
+✅ Apply optimizations before loading models  
+✅ Use debug mode to understand optimization decisions  
+✅ Monitor optimization rates to verify benefits  
+✅ Test with your specific models and workloads  
+✅ Clean up optimizations when done  
+
+### Don'ts
+
+❌ Don't run from parent directory without proper Python path setup  
+❌ Don't apply optimizations to already-loaded models  
+❌ Don't assume all models will benefit equally  
+❌ Don't use with very short sequences (<64 tokens)  
+❌ Don't forget to remove optimizations in production error handlers  
+❌ Don't use with non-Apple Silicon hardware
