Only things you'll be needing is root access and xposed framework (link to xposed below.) Installing Xposed should be easy enough, just make sure you have unknown sources checked in your security settings, then open it up and make sure you install the framework. More often than not, you'll have to do a quick reboot, but after that, head back into xposed and head over to the download modules section and look for this.
After downloading that, just go over to your modules tab and enable it, depending on your device, a reboot may be necessary before it takes effect, in that case just hit restart and you're good to go.
