+- **Purpose-based App Suggestions**: Get app recommendations based on what you want to do (e.g., "video editing", "office work", "programming")
+- **Intelligent Query Matching**: Natural language processing to understand user intent (e.g., "apps to edit videos" → video editing)
 - Search for packages and generate install commands for:
   - pacman (Arch), AUR, apt (Debian/Ubuntu), dnf (Fedora), flatpak, snap
 - Cross-distro support (not limited to Arch)

+### Contributing to Purpose Mappings
+
+The purpose-based suggestions are powered by a community-driven mapping file at `data/purpose_mapping.yaml`. You can help improve the suggestions by:
+
+1. **Adding new purposes**: Add new categories of applications (e.g., "security", "education", "gaming")
+2. **Adding more apps**: Suggest additional applications for existing purposes
+3. **Improving descriptions**: Add better descriptions for applications
+4. **Adding synonyms**: Help improve the natural language processing by adding more phrase mappings
+
+To contribute:
+1. Edit `data/purpose_mapping.yaml` to add your suggestions
+2. Test your changes with `python -m archpkg.cli suggest "your-purpose"`
+3. Submit a Pull Request with your improvements
+
+Example contribution:
+```yaml
+# Add to data/purpose_mapping.yaml

+  - firejail
