+## Configuration de healthchecks
+
+Une part de la configuration de healthchecks se fait dans les variables d'environnement qui lui sont fournies via docker_healthchecks_config_env
+
+Après le premier démarrage il sera nécessaire de créer un admin, qui pourra poursuivre la configuration depuis l'interface web, avec :
+```bash
+docker-compose run healthchecks /opt/healthchecks/manage.py createsuperuser
+```
