"Montar" significa añadir una aplicación completamente "independiente" en un path específico, que luego se encarga de manejar todo bajo ese path, con las _path operations_ declaradas en esa sub-aplicación.

### Aplicación de nivel superior { #top-level-application }

Primero, crea la aplicación principal de nivel superior de **FastAPI**, y sus *path operations*:

{* ../../docs_src/sub_applications/tutorial001_py39.py hl[3, 6:8] *}

"Mounting" means adding a completely "independent" application in a specific path, that then takes care of handling everything under that path, with the _path operations_ declared in that sub-application.

### Top-level application { #top-level-application }

First, create the main, top-level, **FastAPI** application, and its *path operations*:

{* ../../docs_src/sub_applications/tutorial001_py39.py hl[3, 6:8] *}

	path = filepath.Dir(path)
	if v, ok := mountPointCache.Load(path); ok {
		if b, ok := v.(bool); ok {
			return b
		}
	}
	wpath, _ := windows.UTF16PtrFromString(path)
	wvolume := make([]uint16, len(path)+1)

	if err := windows.GetVolumePathName(wpath, &wvolume[0], uint32(len(wvolume))); err != nil {
		mountPointCache.Store(path, false)
		return false
	}
