## Etapas anteriores antes de começar { #previous-steps-before-starting }

Há muitos casos em que você deseja executar algumas etapas **antes de iniciar** sua aplicação.

Por exemplo, você pode querer executar **migrações de banco de dados**.

## Étapes préalables avant de démarrer { #previous-steps-before-starting }

Il existe de nombreux cas où vous souhaitez effectuer certaines étapes **avant de démarrer** votre application.

Par exemple, vous pourriez vouloir exécuter des **migrations de base de données**.
