Nested Module in Yii2

Yii 2.0 General Discussions

Hi All,

I have created a module in my adavanced /frontend / modules

modules

 [color="#FF0000"] admin


   -Admin.php


   controllers


	-AdminController


   Models


	-Admin[/color]





	[color="#9ACD32"]Modules


		user


		    -User.php


		     controllers


				-UserController


		     views


			-user


			    index.php[/color]


 [color="#FF0000"]  Views


	-Admin


		-index.php[/color]

Green colored code is my nested module .

My question is how can i access admin module index.php and nested(user) module index.php respectively.

Any configuration changes needed?

Many Thanks!
