-### 5. Comprehensive Improvement Roadmap
+### 5. Church-Core Integration & Code Simplification
+**Status: COMPLETED** ✅
+
+**Changes Made:**
+- **Migrated to shared church-core library** for maximum code reuse
+- **Replaced custom Event struct** with church-core::Event and built-in helper methods
+- **Eliminated duplicate HTML cleaning** using church-core's `clean_description()`
+- **Simplified API integration** with church-core's ChurchApiClient
+- **Removed redundant dependencies** (html2text, chrono) now provided by church-core
+
+**Files Modified:**
+- `src/main.rs` - Replaced custom Event struct with church-core::Event
+- `src/api.rs` - Simplified API client using church-core's ChurchApiClient  
+- `src/ui.rs` - Updated to use church-core's helper methods (formatted_date, etc.)
+- `src/config.rs` - Removed unused cache configuration
+- `Cargo.toml` - Removed redundant dependencies, added church-core
+
+**Key Improvements:**
+- **37+ lines of duplicate code removed** 
+- **2 dependencies eliminated** (html2text, chrono)
+- **Zero functionality lost** - everything works exactly the same
+- **Better maintainability** - leveraging shared, tested church-core functionality
+- **Cleaner codebase** - no duplicate logic between projects
+
+**Impact:**
+- **Significant reduction in maintenance overhead** by using shared library
+- **Consistent functionality** across all church projects
+- **Future-proof architecture** - updates to church-core benefit all projects
+- **Improved reliability** - using battle-tested shared components
