How can I replace my blue studio 5.5 display screen?

I dropped my phone today and the screen completely cracked at the top and sent a long thin crack down the center of the screen as well. It is still fully functional but I hate having a cracked screen. I wanted to buy the screen replacement and install it myself as I know it will be cheaper than sending it off for repairs. I can't find a tutorial for this on YouTube before anyone suggests. Please give me step by step instructions on how to replace the LCD display screen please? How easy is it because I am the worst at technical computer/phone repairs so I am nervous about doing something like this. I would appreciate any help I can get, thank you.
