How do I take care of an orchid plant?

My mother bought me this beautiful orchid because she knows they're one of my favorite flowers, which was really sweet of her! But I have ZERO gardening skills! I read the little tag on it and it says to feed it twice a month, keep it in a well lit room but avoid direct sunlight, and to keep the soil moist but not to let it sit in water and to avoid water at the "crown" of the plant... WTF is the crown of the plant?! What kind of food to feed it? ANY tips on how to keep my orchid alive will help!
