# 3. Add modifiers. Some modifiers for local execution are:
#      Ex. disk_cache -- Use a local cache
#      Ex. public_cache -- Use TF's public cache (read-only)
#      Ex. public_cache_push -- Use TF's public cache (read and write, Googlers only)
#      Ex. rbe        -- Use RBE for faster builds (Googlers only; see below)
#      Ex. no_docker  -- Disable docker on enabled platforms

Usarlo en tu editor es lo que realmente te muestra los beneficios de FastAPI, al ver cuán poco código tienes que escribir, todos los chequeos de tipos, autocompletado, etc.

## Instalar FastAPI { #install-fastapi }

El primer paso es instalar FastAPI.

Asegúrate de crear un [entorno virtual](../virtual-environments.md){.internal-link target=_blank}, actívalo, y luego **instala FastAPI**:
