Default Screen Replacement (Digitizer and glass)

Ok so ive cracked my S4 Active's glass (digitizer is fine) so I bought a new digitizer and glass for it because j didnt want to go through all the trouble of removing the glass from the glue and all that. But I cant find a decent tutorial anywhere on how to replace this. Can someone direct me towards one?
