Start simple and learn as you go. Watch you tube videos between now and then.
In short: get the skin off. Then get the meat off the bones and into the freezer bags/freezer paper whatever you're wrapping in.
Plenty of great you tube videos and then it's just experience and learning what works well and what doesn't.
I've cut up well over 100 deer in the last ten years. I've done allot of things that I won't do again.
Eventually you'll figure out what you like and what works for you. I can't recommend YouTube enough for learning. You'll see very good videos with allot of details and tips.
On another note. Study up on tracking and blood trailing. It's not uncommon to have to come back in the morning to start the trail again. Once you've put a shot on a deer, you have to do everything you can to follow up and find it.
Good luck!
Oh. And quality, sharp knives will make it a much simpler process.
