How to get Minecraft Story mode?

I luv minecraft, Like a lottt.
I heard about this new thing called Minecraft Story mode and i want to know more about it. Apparently its this episode thing. I have no idea how to download it or anything. Also i read on a website that it was going to be released in 2015, so i guess thats now right?

Look it up on google

Technically speaking, its not actually part of Minecraft. Its a completely separate game that someone built using Minecraft's game engine.
