Making a new lockscreen.

So I followed a tutorial(the video by h_zee) for creating a lockscreen for MIUI and finished the XML file and image editing, but the end of the tutorial doesn't show where to stick the files or what to do with them. This is my first time doing any sort of creation so I'm a bit lost on where to put the manifest, lockscreen wallpaper, locker/slider, and the lockscreen sounds. I'd just like to be able to drop them onto the phone and get it over with but I can't find anything except tutorials on how to edit existing themes(which I didn't do). It sucks to be stuck after I finished figuring out the XML stuff.

Thanks.

(If it matters, I'm using an MI3 with the current version of MIUI)
