+## Les variables qui fournissent des valeurs
+
+Il peut être intéressant de retrouver facilement des variables sans connaitre le chemin complet mais en utilisant le contenu du paramètre "provider".
+C'est particulièrement utile si un service peut être fournit par plusieurs services. Les variables n'auront donc pas le même nom. Utiliser ce paramètre, permet donc de retrouver facilement la variable.
+
+Pour déclarer :
+
+```
+<variable name="my_variable" provider="my_function"/>
+```
+
+Dans le code de l'application, on pourra retrouver le chemin de la variable en faisant :
+
+```
+print(await config.information.get('provider:my_function'))
+```
+
+Pour les variables inclusent dans une famille dynamique, le chemin de la variable sera un template comme ceci "rougail.family_{suffix}.my_variable_{suffix}". Il vous suffit de remplacer "{suffix}" par le suffix voulu de la famille dynamique.
