**Khuyến khích** bạn viết hoặc sao chép code, sửa và chạy nó ở local.

Sử dụng nó trong trình soạn thảo của bạn thực sự cho bạn thấy những lợi ích của FastAPI, thấy được cách bạn viết code ít hơn, tất cả đều được type check, autocompletion,...

## Cài đặt FastAPI

Bước đầu tiên là cài đặt FastAPI.

Với hướng dẫn này, bạn có thể muốn cài đặt nó với tất cả các phụ thuộc và tính năng tùy chọn:
