Beginner Question On Tarot, upright cards Options

So I just baught my first deck "The Rider" and a book called "The tarot:History,Symbolism,and Divination" by Robert M. Place and I have a very simple and basic question: In order to get a proper reading do all the cards have to be pointed upright and if they do turn out to be downward then what do you do?

Well some decks are supposed to be used with the cards upright and if you have any instructions with them, they will say this somewhere.

Many decks have cards that can be used where the cards are a mix of upright and reversed or ill-dignified, if you have a little booklet with them , it should tell you both sets of meanings, one for upright, another for upside down cards.

If not, I recommend getting hold of Tarot, Plain and SImple by Anthony Lewis for many decks unless the card instructions mention a particular book that was written especially for that deck.
