The main [Tutorial - User Guide](../tutorial/index.md){.internal-link target=_blank} should be enough to give you a tour through all the main features of **FastAPI**.

In the next sections you will see other options, configurations, and additional features.

The next sections are **not necessarily "advanced"**.

And it's possible that for your use case, the solution is in one of them.

Here are the introductory sections and the tutorials to learn **FastAPI**.

concepts you should probably keep in mind when deploying a **FastAPI** application (although most of it applies to any other type of web application).

You will see more details to keep in mind and some of the techniques to do it in the next sections. ✨...

But you can still document it as described in [Additional Responses in OpenAPI](additional-responses.md){.internal-link target=_blank}.

Vous pourriez diviser en différentes sections comme avec les burgers, d'abord le salon, puis la cuisine, etc. Mais vous n'attendez 🕙 rien, vous ne faites que nettoyer et nettoyer, la séparation en sections ne changerait rien au final.

Cela prendrait autant de temps pour finir avec ou sans sections (concurrence) et vous auriez effectué la même quantité de travail.
