It's pretty simple most Ham come with the detections how long to cook it and what not you can glaze it your self and stick that beauty in the oven,I like to pamper mine and cover it with foil and cook it with love
I cooked mine in a crock pot since I had a turkey in the oven for Thanksgiving. The Ham was so tender and juicy in the crockpot. We did take it out and out it in a oven safe dish for the glaze for the last 10 mins or so. Super yummy!
I just bought a nonspiral ham and glazed it with some butter, about 4 tbsp of sugar, 2 tsp of vanilla, 2 cups of grated pecans and a little powdered sugar. It sounds funny but it was absolutely amazing. You gotta caramelize the glaze first, but it's soooo worth it.
