I would recommend an excellent resource - ptarot.com - if you are interested in tarot or are looking for a way to deepen your knowledge in this area. There is everything there: from basic information for beginners to advanced techniques and layouts. I myself used this site https://ptarot.com when I was looking for detailed descriptions of cards and their meanings. It was very helpful in understanding the nuances and details of layouts, especially if you want to not only read the cards, but understand them more deeply.
