Git et les espace partagés

- Quelle doctrine sur le stockage de dépôts `Git` dans des espaces partagés ?
- Place ici ou dans la formation bonnes pratiques ? (ou les deux)

No file, test, or entry point is named. First clarify the doctrine for storing Git repositories in shared spaces and decide whether it belongs here, in the bonnes pratiques training, or both. Done means the placement and guidance are agreed and documented.
