+# Spécification de la Rose dorée (Gilded Rose)
+
+Bonjour et bienvenue dans l'équipe de la Rose dorée.
+
+Comme vous le savez, notre petite taverne située à proximité d'une cité importante est dirigée par l'amicale aubergiste Allison.
+
+Nous achetons et vendons uniquement les meilleurs produits.
+Malheureusement, la qualité de nos marchandises se dégrade constamment à l'approche de leur date de péremption.
+
+Un système a été mis en place pour mettre à jour notre inventaire.
+Il a été développé par Leeroy, une personne pleine de bon sens qui est partie pour de nouvelles aventures.
+
+Votre mission est d'ajouter une nouvelle fonctionnalité à notre système pour que nous puissions commencer à vendre un nouveau type de produits.
+
+Mais d'abord, laissez-moi vous présenter notre système :
+
+- Tous les éléments ont une valeur `sellIn` qui désigne le nombre de jours restant pour vendre l'article.
+- Tous les articles ont une valeur `quality` qui dénote combien l'article est précieux.
+- À la fin de chaque journée, notre système diminue ces deux valeurs pour chaque produit.
+
+Plutôt simple, non ?
+
+Attendez, ça devient intéressant :
+
+- Une fois que la date de péremption est passée, la qualité se dégrade deux fois plus rapidement.
+- La qualité (`quality`) d'un produit ne peut jamais être négative.
+- "Aged Brie" augmente sa qualité (`quality`) plus le temps passe.
+- La qualité d'un produit n'est jamais de plus de 50.
+- "Sulfuras", étant un objet légendaire, n'a pas de date de péremption et ne perd jamais en qualité (`quality`)
+- "Backstage passes", comme le "Aged Brie", augmente sa qualité (`quality`) plus le temps passe (`sellIn`) ; La qualité augmente de 2 quand il reste 10 jours ou moins et de 3 quand il reste 5 jours ou moins, mais la qualité tombe à 0 après le concert.
+
+Nous avons récemment signé un partenariat avec un fournisseur de produit invoqué ("Conjured").
+Cela nécessite une mise à jour de notre système :
+
+- les éléments "Conjured" voient leur qualité se dégrader de deux fois plus vite que les objets normaux.
+
+Vous pouvez faire les changements que vous voulez à la méthode `updateQuality` et ajouter autant de code que vous voulez, tant que tout fonctionne correctement.
+Cependant, nous devons vous prévenir, vous ne devez en aucun cas modifier la classe `Item` ou ses propriétés car cette classe appartient au gobelin à l'étage qui entrerait dans une rage instantanée et vous tuerait sans délai : il ne croit pas au partage du code.
+(Vous pouvez ajouter une méthode `updateQuality` et des propriétés statiques dans la classe `Item` si vous voulez, nous vous couvrirons)
+
+Juste une précision, un produit ne peut jamais voir sa qualité augmenter au-dessus de 50, cependant "Sulfuras" est un objet légendaire et comme tel sa qualité est de 80 et elle ne change jamais.
