How to reassemble iPod touch 4th generation

Hello,

I seen the guides on how to replace parts for the ipod 4th gen., but I don't see a guide on how to put them back togeather. A guide for putting them back togeather would be great because I have no idea what I'm doing..lol! My son dropped his and cracked the glass, still works fine though. I would like to try and fix it myself. I've never done this before but I do believe I can follow your how to guides, but putting it back togeather looks a little difficult. Reattaching the wires under the plates and how to you get the back to stick again? Maybe be silly but I would really like to see how you would put it back togeather.

Thank you!
