# Subdependências { #sub-dependencies }

Você pode criar dependências que possuem **subdependências**.

Elas podem ter o nível de **profundidade** que você achar necessário.

O **FastAPI** se encarrega de resolver essas dependências.

## Primeira dependência "dependable" { #first-dependency-dependable }

Você pode criar uma primeira dependência ("dependable") dessa forma:
