+# PlantUML
+
+alternative à starUML pour générer des diagrammes UML.
+
+Différence principale : du texte qu'on peut écrire dans un éditeur de texte plutôt qu'un cliquodrome.
+
+Pour l'instant pas de rendu possible dans le markdown du serveur git.
+
+Vous avez la documentation en pdf.
+J'ai mis des exemples dans le répertoire exemples.
+
+En TP je vais vous demander d'utiliser plantUML pour réaliser vos diagrammes.
+
+Normalement plantUMl est installé sur les machines de l'IUT.
+Sinon pour l'installer, il suffit de récupérer le jar.
+Il est assez facile de l'intégrer à votre éditeur normalement.
+
+À partir du jar, vous pouvez générer vos diagrammes (privilégiez un format vectoriel comme svg).
+
+Si il y a un problème dans le placement par défaut, vous pouvez essayer de regrouper des choses avec le mot clé together, ou d'indiquer le sens des flèches.
+
+L'idée est quand même de laisser l'outil vous faire un rendu automatique.
+
+
+
+## Alternative similaire à PlantUML
+
+Il existe une alternative qui elle est rendue correctement dans du markdown sur le serveur git du département: mermaid.
+Toutefois cet outil semble être moins utilisé que plantUML avec encore pas mal de parties instables.
+
