Hunting from up high is different. Everybody reacts differently to being up in the air.
I advise you to practice installing the thing on a tree while standing firmly on the ground till you figure out the "right way" to do it.
Think about the wind as far as stand placement in an area.
Try to stay back from the area you think the deer will come by. Give your self at least a ten yard shot.
Study the animals anatomy with respect to where to aim, it is different from above.
Try to use a set up (bow / arrow / broadhead) that gives the best penetration, trying for a pass thru. You really want a hole in the bottom for a blood trail.
Think about your comfort and how you need to sit / stand / draw when you place the stand in a tree. By having the stand on the backside of the tree, you have a bit more cover....but it is harder to shoot, directly facing the proposed shoot zone may also make it a bit clumsy. Usually canting the stand a bit, (depending on whether you are right handed or left handed) around the tree can make things much more comfortable.
Try to have some cover near or beyond you (as seen from the ground) so you don't show up too well, think about how you will look if the animal is approaching from above (hill or mountainside) or across an open area if that is a possibility.
Always put your stand up in a sturdy tree (a friend had a whole tree come down with him in it)
Wow.....and I thought this was easy.
You mentioned a stand. How are you gonna get the stand up there ? Gotta start thinking about steps of some sort. That is another post to start !
and always use a fall restraint device.
