!!! note "Detalles Técnicos"
    `Cookie` es una clase "hermana" de `Path` y `Query`. También hereda de la misma clase común `Param`.

    Pero recuerda que cuando importas `Query`, `Path`, `Cookie`  y otros de `fastapi`, en realidad son funciones que devuelven clases especiales.

# Istio Installer

Note: If making any changes to the charts or values.yaml in this dir, first read [UPDATING-CHARTS.md](UPDATING-CHARTS.md)

Istio installer is a modular, 'a-la-carte' installer for Istio. It is based on a
fork of the Istio helm templates, refactored to increase modularity and isolation.

Goals:
- Improve upgrade experience: users should be able to gradually roll upgrades, with proper

Au moment où j'ai commencé à créer **FastAPI** lui-même, la plupart des pièces étaient déjà en place, la conception était définie, les exigences et les outils étaient prêts, et la connaissance des normes et des spécifications était claire et fraîche.

## Futur

À ce stade, il est déjà clair que **FastAPI** et ses idées sont utiles pour de nombreuses personnes.
