My iphone 5 screen cracked, what do i do?

I accidentally cracked my iphone's screen today and its pretty bad, but the phone can still be used. I don't want to get a new phone since the one i have right now works perfectly. I want to just replace the screen but i don't know i to do it.

You can get screen replacement kits. I just got a couple for $5 each from one of those discount deal sites. Try ebay.
