+- Access docs at `/admin/api-docs` (requires admin login)
+- **Automatic generation**: GitHub Actions automatically updates docs when API specs change on `main` branch
+- **Configuration files**:

+  - `config/initializers/rswag_ui.rb` - Swagger UI config
+  - `config/initializers/rswag_api.rb` - API serving config

 5. See `docs/authorization.md` for policy patterns
 
+### Adding/Updating API Endpoints
+1. Create/update controller action in `app/controllers/api/`
+2. Add request spec in `spec/requests/api/` - this generates the API docs
+3. Test locally: `OPENAPI=1 bundle exec rspec spec/requests/api`
+4. Check generated docs at `/admin/api-docs` (requires admin login)
+5. Docs auto-update on `main` branch via GitHub Actions
+6. To exclude specs from docs, add `openapi: false` to the describe block
+7. See `docs/api_documentation.md` for more details

 ### Running Tests for Specific Features
 - Authorization policies: `bundle exec rspec spec/policies/`
+- API endpoints: `bundle exec rspec spec/requests/api/` (or with `OPENAPI=1` to generate docs)
 - Calendar preferences: `bundle exec rspec spec/models/calendar_preference_spec.rb`
 - Template rendering: `bundle exec rspec spec/services/calendar_template_renderer_spec.rb`
 - Preference resolution: `bundle exec rspec spec/services/preference_resolver_spec.rb`
