## Auto-Documentation Process

For new features, documentation should be created:

1. **During implementation** (not after):
   - When creating a new feature, create its doc file
   - Use the template from docs/templates/
   - Update README features list

2. **In the same commit**:
   - Code changes + doc changes in same PR
   - Review docs alongside code

3. **Checklist**:
   - [ ] Feature doc created in docs/features/
   - [ ] API endpoints documented in docs/api/
   - [ ] README updated with feature link
   - [ ] Architecture doc updated if needed

## Maintenance

- **Monthly review**: Check for outdated docs
- **Version tracking**: Tag docs with app version
- **OpenSpec integration**: Link to OpenSpec changes for context

## Tools

- **Markdown**: All docs in Markdown
- **Mermaid**: Diagrams in Mermaid syntax
- **FastAPI docs**: Auto-generated from code
- **GitHub Pages**: Optional static site generation
