Nintendo DS Lite Housing Shell Replacement- I need instructions! Please help!

I bought a pink DS Lite about a year ago, and recently decided that white would look nicer..... well long story short, I bought a replacement housing shell on ebay. All the parts are there and I've got the screw drivers and all. My problem is that the person that sent it shipped it out of Hong Kong so the directions are all in chinese! I've looked all over the internet and can't seem to find any directions on how to change it out- Please help me :( Ima fool!
