**Spoiler alert**: туторіал - посібник користувача містить:

* Оголошення **параметрів** з інших місць як: **headers**, **cookies**, **form fields** та **files**.
* Як встановити **перевірку обмежень** як `maximum_length` або `regex`.

* A new link should be at the top of its list.
* The link URL should work (it should not return a 404).
* The content of the link should be about FastAPI.
* The new addition should have these fields:
    * `author`: The name of the author.
    * `link`: The URL with the content.
    * `title`: The title of the link (the title of the article, podcast, etc).
