I did a google search and read each and everyone, taking what I thought was the best advice to pick and choose what I thought was important. Also, if you're buying a new box, it will have instructions.

My advice: secure everything! Anything that can bounce around, WILL bounce around. I cover every inch of the frame with foam pipe insulation, and remove anything that can move around and pack seperately. Use spacers in the fork AND rear drop outs, and I was much happier with my packing job when I took my rear derailleur off (just unscrewed the whole derailleur hanger, so there was no adjustments when I put it back on.)
