Need help with rooting/Xposed... topic

I have my G2 coming in the mail in a couple days and I really want Xposed on there based off of what I have seen of it. I would like to clean up the notifications and add the recent apps button rather than the menu button...

What are the full steps I need to do to get Xposed working on my new phone?

I have never rooted any of my phones before so I would like some help if y'all wouldn't mind. Thanks in advance!!
