# Mystic This crate can be used either as a CLI, see `examples/cli`, or as a library. It uses ChatGPT for interpretation, but this is not required. If you are using that then you'll need a `.env` containing your `CHATGPT_KEY`, ie: ```sh #.env at root CHATGPT_KEY=foo ``` ## Supported Categories ### Tarot ```rs let mut deck = TarotDeck::new(); deck.shuffle(); let spread = spread::PastPresentFuture::new(&mut deck); let gpt = ChatGptInstance::new()?; println!("interpreting your spread...\n{}", spread.print()); let result = spread.interpret(&gpt).await?; ```
