How do I replace my digitizer screen?

I cracked my lg US730 screen about a month or two ago, and it started to get annoying. So, I did some research about which part of my phone was cracked and found that I would have to replace the glass digitizer screen. I have already purchased the digitizer screen and have the proper tools, but I can not find a replacement guide anywhere! So please help me! Any assistance would be appreciated. Preferably, if you could include details and pictures, that would be great! I would really like to fix this soon. Thanks!
