I want to put LoadMore/PullToRefresh feature to my app via [this](https://github.com/shontauro/android-pulltorefresh-and-loadmore/tree/c4a076d938d49a7c449f9a1b927ff730c7139d6b) library made by shontauro. I've tried it like it's said to be done in README, but I think that something is missing there. I don't understand the logic at all. I've put some libraries to my projects in the past (appcompat support library, other .jar libraries etc.) but I didnt figure out what is the system of this type of libraries.

Do you have any idea how to accomplish that?
