Having checked your profile I see it is The Psychic Tarot Oracle Deck.
I would start by going through the cards, looking at the pictures, and writing down whatever comes into your head when you look at the cards, or what you think the picture is trying to tell you.
That is the advice I wish I had found when I started.
By the time you have done that, I'm sure someone more experienced than me will jump in with what to do next.
Oh, and as advised by the esteemed Umbrae on this forum, use a pencil. Don't know why it makes a difference but it certainly did for me!!
