- Open MinIO URL on the browser, lets say <http://localhost:9000/>
- Click on `Login with SSO`

Et vous obtenez aussi de la vérification d'erreur pour les opérations incorrectes de types :

Ce n'est pas un hasard, ce framework entier a été bâti avec ce design comme objectif.

You also get error checks for incorrect type operations:

This is not by chance, the whole framework was built around that design.
