You need to do a lot of researching on the internet. When my daughter got her box turtle, I found several good sites on identification, sexing, raising and breeding.
Keeping a box turtle properly isn't as easy as it sounds. Contrary to their common name (BOX turtle), they aren't to be kept in a "box". Mine is kept in a very LARGE plastic tub and the only reason I don't have her in an outdoor habitat is because of stray cats that get in my yard.
She is almost 5 yrs old and I've had her for 3 yrs now so it looks like she'll be with me the rest of her life.
As for what to feed, you need to identify what species it is. Some are carnivores, some herbivores and some omnivores. Same thing with the habitat...sand, loamy soil...etc. I don't recommend wood shaving though because it can cause serious injury to the eyes. Mine has about three inches of garden soil topped with another inch or two of grass clippings. But you need to find out what kind you have and what their natural habitat is to know the best way to set up it's home.

BTW, I have a Western Ornate.
