-# ⚡ Lightning Policy Manager
+# Lightning Policy Manager

 Next-generation Lightning Network channel fee optimization with advanced inbound fee strategies, machine learning, and automatic rollback protection.

-## 🚀 Overview
+## Overview

 Lightning Policy Manager is an intelligent fee management system that enhances the popular **charge-lnd** tool with:
- ✅ **Advanced inbound fee strategies** (beyond simple discounts)
- ✅ **Automatic rollback protection** for safety
- ✅ **Machine learning optimization** from historical data
- ✅ **Revenue maximization focus** vs simple rule-based approaches  
- ✅ **High-performance gRPC integration** with REST fallback
- ✅ **Comprehensive security** with method whitelisting
- ✅ **Complete charge-lnd compatibility**
