### `startup` y `shutdown` juntos

Hay una gran posibilidad de que la lógica para tu *startup* y *shutdown* esté conectada, podrías querer iniciar algo y luego finalizarlo, adquirir un recurso y luego liberarlo, etc.

Hacer eso en funciones separadas que no comparten lógica o variables juntas es más difícil ya que necesitarías almacenar valores en variables globales o trucos similares.

    * Também é possivel revisar as traduções já existentes.
* Para propor novas seções na documentação.
* Para corrigir um bug/questão.
* Para adicionar um novo recurso.
