   Copy after login

3. Configure access routing
   Add the following routing configuration in the config/routes.php file:

   use AppDocDocGenerator; Router::get('/api/docs', function (DocGenerator $docGenerator) { return $docGenerator->generate(); });

   Copy after login

4. Generate API documentation
