HELP: Installing Kali Linux in Acer Chromebook C720 Core i3

Hi folks, just wanted to install Kali Linux natively (don't want virtualization or anything like it) in this chromebook can some of you shed some light how to do it? I've search so many articles about it, but I don't want to start messing with it without the assurance of what will happen if something came up wrong. I'm new to Linux so I'm a lil bit scared, hope you help me with this one TIA.
