+## Preset System
+
+The addon features a sophisticated three-tier preset system:
+
+### Storage Locations (Priority Order)
+
+1. **Blend File Storage** (Highest Priority)
+
+   - Presets stored in scene custom properties
+   - Travel with your .blend file
+   - Perfect for project-specific presets
+
+2. **Persistent File Storage** (Medium Priority)
+
+   - Survives addon updates and Blender upgrades
+   - Stored in Blender's user config directory
+   - Shared across all blend files
+
+3. **Legacy File Storage** (Lowest Priority)
+   - Backward compatibility with old addon versions
+   - Automatically migrated to persistent storage
