How to use Google Docs Offline?

Hey, I’ve been using Google Docs online for my office works and sometimes I wanna use them offline too. Can someone tell me how to use Google docs offline? Is it even possible?

I have been using this for a while and works very well. But if you need an Ms Office alternative please consider something like
