 In most cases, it is enough to import only `Web.Pixiv`. If you want to use lenses to access and operate data types,
 you should import `Web.Pixiv.Types.Lens` as well. Pixiv API requires authentication before being accessed, thus the `PixivT` monad transformer provides an user-friendly and thread-safe interface
-to manage, and renew access token on demand, where you just need to give the username and password of your pixiv account.
