They should have come with a book that tells the meanings of the cards. The meanings can vary from one deck to the next, although there are usually several similarities and overlapping themes. You can also Google the meanings to get a broader view and see which ones seem to fit with the images on your cards.
Or you could check out Daniel Burns here on Medium - he writes a lot of detail about the cards. His ID is @Vibration101
I'm considering offering a foundational Tarot group course again and if you'd like to be on the waiting list, let me know. I don't have details of the fees or times yet.
If you would like to go deeper with learning and understanding the Tarot, and strengthen your intuition and develop the skill of weaving together the story, you can book private sessions through my website, either as one-off appointments, or in blocks of four paid at once, at a discounted rate. You can read about both (guidance, and mentorship program) at http://libertyforrest.com
