HMVC - set default route

Hi, I'd like some help please. I'm using CI v.3.0.2 and I have set up HMVC modularity from wiredesignz, so my folder structure look like this

Code:

- application
---- modules
-------- posts
----------- controllers
--------------- Admin.php
--------------- Post.php
----------- models

In that source structure, you have a folder "posts" (plural), and a controller "Post.php" (singular)
