When ordering a new instrument, you may find on arrival that the bridge (the small piece of wood, usually maple, that lifts the strings above the body - pictured) is lying down, often wrapped in protective paper.
This is the only part of 'setting up' that a factory do not do, simply because in transit there's the possibility of the bridge falling down and potentially damaging the instrument.
The good news is, even if it falls down by accident, they're really easy to pop back into place. It's easier to watch than to try and describe it in words, so see the video below for more help -
