 *Ce code n'a pas été testé dans un autre environement que le miens, il est publié par simple soucis de transparence et d'audit*
 
 Utilise l'API BMA pour l'extraction des clés publiques ḡ1 membres et non membres, ainsi que l'API ElasticSearch de Cesium+ pour la récupération des soldes par soucis d'optimisation.
-Les variables d'environnements se trouvent simplement en début de script. Il est nécessaire de les modifier avant l'execution.
 
 A exécuter dans un environnement Bash Debian/Ubuntu.
 
+## Prérequis
+
+Copiez le fichier .env.example en .env et adaptez les variables selon votre usage.
+
 ## Exécution
