 ## Installation
-Pour télécharger le projet vous pouvez simplement utiliser la commande `git clone https://gitea.galaxynoliro.fr/KuMiShi/Optim_Metaheuristique.git` ou récupérer le fichier `.zip` du projet et l'extraire.
+Le projet a été concu à l'aide du *Python packet manager* ***UV***, il est préférable d'utiliser celui-ci pour ca facilité d'utilisation. **UV** peut être installé via le [site internet officiel](https://docs.astral.sh/uv/getting-started/installation/#installing-uv).
