In certain conditions , we want the first page of our application do directly into actual applications , but we want to explain in detail the application . To do that we can redirect the application to a specific page by changing main.php at the directory config . 'defaultController' = 'controller/action' , Example :     return array ( ...   ' defaultController ' =>home /index , ...   ); Thx
