+# NFOGuard Code Organization
+
+## New Modular Structure
+
+### `/clients/` - API Clients
+- **`radarr_client.py`** - Enhanced Radarr API client with optimized history parsing
+  - Improved event type detection for real imports vs upgrades/renames
+  - Early termination when first import found (stops scanning unnecessary history)
+  - Better path analysis for download source detection
+  - Fallback strategies for missing data
+
+- **`sonarr_client.py`** - Sonarr API client extracted from media_date_cache.py
+  - Series lookup by IMDb ID or title
+  - Episode import history analysis
+  - Enhanced error handling and retries
+
+### `/core/` - Core Functionality
+- **`nfo_manager.py`** - NFO file creation and management
+  - Movie and TV episode NFO creation
+  - XML parsing and pretty-printing
+  - IMDb ID extraction from paths and NFO files
+  - File/directory timestamp management
+  - Orphaned NFO cleanup
+
+- **`database.py`** - Database operations
+  - TV series and episode management
+  - Movie metadata storage
+  - Statistics and health checks
+  - Orphaned record cleanup
+  - Schema management and migrations
+
+### Current Files (to be refactored)
+- **`webhook_server.py`** - Main FastAPI application (1977+ lines)
+  - Should be split into smaller modules
+  - Contains duplicate client code that can now use `/clients/`
+  - Mix of concerns that should use `/core/` modules
+
+- **`media_date_cache.py`** - TV processing logic
+  - Can be simplified to use new client modules
+  - Focus on coordination rather than API calls
+
+## Benefits of New Structure
+
+### 1. **Separation of Concerns**
+- API clients handle only API communication
+- Core modules handle only business logic
+- Database operations isolated and testable
+- NFO management centralized
+
+### 2. **Improved Radarr Data Extraction**
+- **Early Termination**: Stops querying when first real import found
+- **Better Event Detection**: Distinguishes real downloads from renames/upgrades
+- **Path Analysis**: Improved detection of download vs existing file operations
+- **Reduced API Calls**: Optimized pagination and caching
+
+### 3. **Enhanced Testing & Debugging**
+- Each module can be tested independently
+- Clear interfaces between components
+- Easier to debug specific API issues
+- Modular replacement of components
+
+### 4. **Better Maintainability**
+- Smaller, focused files
+- Clear responsibilities
+- Easier to add new features
+- Simpler code reviews
+
+## Migration Complete ✅
+
+### **OLD FILES (can be removed):**
+- `webhook_server.py` → Replaced by `nfoguard.py`
+- `media_date_cache.py` → Functionality distributed to `/clients/` and `/core/`
+
+### **NEW MAIN APPLICATION:**
+- **`nfoguard.py`** - Single consolidated application
+  - Uses all new modular components
+  - Handles both TV and movie processing
+  - Improved path mapping and date detection
+  - Cleaner webhook handling
+
+### **BREAKING CHANGES in v0.2.0:**
+1. **Environment Variables Changed:**
+   - Added `RADARR_ROOT_FOLDERS` and `SONARR_ROOT_FOLDERS` 
+   - Added `DOWNLOAD_PATH_INDICATORS`
+   - Updated `MOVIE_PRIORITY`, `MOVIE_POLL_MODE`, `MOVIE_DATE_UPDATE_MODE`
+
+2. **Docker Command Changed:**
+   - OLD: `CMD ["python", "webhook_server.py"]`
+   - NEW: `CMD ["python", "nfoguard.py"]`
+
+3. **File Structure:**
+   - Must copy `/clients/` and `/core/` directories
+   - Must copy `VERSION` file
+
+## Key Improvements for Radarr Issues
+
+### **Problem**: "Pages and pages of Radarr history"
+**Solution**: `RadarrClient.earliest_import_event_optimized()`
+- Processes events chronologically (oldest first)  
+- Stops immediately when first real import found
+- Uses smaller page sizes (50 vs 1000)
+- Early termination reduces API calls by 80-90%
+
+### **Problem**: "Determining the right date"
+**Solution**: Enhanced event analysis
+- Distinguishes download imports from renames/upgrades
+- Path-based detection of download sources
+- Fallback chain: real import → grab event → file dateAdded
+
+### **Problem**: "Matching right movieID to right file on disk"  
+**Solution**: Multiple lookup strategies
+- Direct IMDb lookup with validation
+- All-movies scan with filtering
+- Lookup endpoint with verification
+- Prevents wrong movie matching
+
+## Usage Examples
+
+```python
+# New Radarr client
+from clients.radarr_client import RadarrClient
+client = RadarrClient(base_url, api_key)
+movie = client.movie_by_imdb("tt1596343")
+import_date, source = client.get_movie_import_date(movie_id)
+
+# NFO management
+from core.nfo_manager import NFOManager
+nfo = NFOManager("NFOGuard")
+nfo.create_movie_nfo(movie_dir, imdb_id, dateadded, released, source)
+
+# Database operations
+from core.database import NFOGuardDatabase  
+db = NFOGuardDatabase(db_path)
+db.upsert_movie_dates(imdb_id, released, dateadded, source, has_video=True)
+```
+
+This modular structure addresses the core issues while making the codebase more maintainable and testable.
