+## Key Features
+
+### Intelligent Content Organization
+- **AI-Powered Tagging**: Automatic classification with geographic, topical, and source tags
+- **Hierarchical Filtering**: Multi-level filtering by location (country → region → city), categories, and content types
+- **Smart Search**: Advanced filtering with suggestions based on tag relationships and usage patterns
+- **Legacy Migration**: Seamless upgrade from simple country-based filtering to comprehensive tag-based system
+
+### Advanced Analytics
+- **Reading Statistics**: Track reading time, completion rates, and engagement patterns
+- **Content Analytics**: Source performance, tag usage, and trending topics analysis
+- **Geographic Insights**: Location-based content distribution and reading preferences
+- **Goal Tracking**: Personal reading goals with progress monitoring
+
+### Flexible Article Display
+- **Compact View**: Title, excerpt, tags, and action buttons for quick browsing
+- **On-Demand Loading**: Full content, AI summaries, and source links as needed
+- **Visual Tag System**: Color-coded, hierarchical tags with click-to-filter functionality
+- **Reading Status**: Visual indicators for read/unread status and progress tracking
+
+### Enhanced Sharing
+- **Multiple Formats**: Text, Markdown, HTML, and JSON export options
+- **Custom Templates**: User-configurable sharing formats
+- **One-Click Operations**: Copy to clipboard with formatted content
+- **Privacy Controls**: Configurable information inclusion in shared content

+## Configuration
+
+The application uses a comprehensive configuration system via `config.toml`:
+
+- **AI Settings**: Configure Ollama integration for summaries and tagging
+- **Display Preferences**: Default views, themes, and UI customization
+- **Analytics**: Control data collection and retention policies
+- **Filtering**: Smart suggestions, saved filters, and geographic hierarchy
+- **Sharing**: Default formats and custom templates
+
+See the example configuration in the project for detailed options.
+
+## Migration from Legacy Systems
+
+The application includes automatic migration tools for upgrading from simpler filtering systems:
+
+- **Country Filter Migration**: Automatic conversion to hierarchical geographic tags
+- **Data Preservation**: Maintains historical data during migration
+- **Backward Compatibility**: Gradual transition with user control
+- **Validation Tools**: Ensure data integrity throughout the migration process
+
+## Future Roadmap
+
+The project is evolving through three phases:
+1. **Phase 1**: High-performance Rust backend with advanced filtering and analytics
+2. **Phase 2**: CLI application for power users and automation
+3. **Phase 3**: Migration to Dioxus for a full Rust stack
+
+See `ROADMAP.md` for detailed development plans and architectural decisions.
