How to replace an iPhone's 5 screen?

I'm trying to replace my iphone's 5 shattered screen myself to save some money. I understand the risks and the fact that it voids the warranty. I'm trying to figure out if I need to replace the screen alone or if I should get the LCD part too just in case. And if anyone has good tutorials to share, let me know. Thanks.

My screen looks like this now:

You're gonna wanna replace the whole thing. It costs $80 for Apple to just give you a new one so just do that.

Ok, again, I know I could go to Apple and get it fixed… But I'm goig to give it a shot myself. I know, I know; its risky.

Anyway, anyone that can help me out?
