How to create modules for YII2 correctly?

Question

Yii

I am creating an admin panel for the site and the question arises of how to organize everything correctly.
Approximate plan
site.ru/index.php?r=admin //The admin panel itself with the output of all the necessary information
site.ru/index.php?r=admin/posts/[index|edit|delete|view] //The post management page
site.ru/index.php?r=admin/users/[index|edit|delete|view] //User management page
1. I create the admin module
2. I create the postController and userController controllers in the admin\controllers\ folder
3. I create Models and Crud for post and user
In the right direction I think or am I wrong?

Answer 1

right.
modules are also made through gii.
One more thing, most likely for controllers in the admin module, you'd better inherit from a controller with admin access only.
