+## Configuration
+
+> Astuce : lorsqu'on exécute directement la crate `backend` à des fins de développement, le système de configuration n'utilisera pas l'éventuel fichier `.env` situé à la racine du workspace Rust. Pour éviter de dupliquer le fichier `.env`, il est possible de créer un lien symbolique vers le fichier `.env` de la crate `backend` :
+
+```bash
+cd crates/backend
+ln -s ../../.env .env
+```
+
 ## Développement
 
 Pour lancer le serveur en mode développement, exécutez la commande suivante :
