 Si le type de base de données sélectionné est SQLite, la variable `DJANGO_DB_HOST` sera utilisée en guise de chemin vers
 le fichier de base de données (par défaut, `db.sqlite3`).
 
 En développement, il est recommandé d'utiliser SQLite pour des raisons de simplicité. Les paramètres de mail ne seront
-pas utilisés, et les mails qui doivent être envoyés seront envoyés dans la console. Les intégrations mail et Matrix
+pas utilisés, et les mails qui doivent être envoyés seront envoyés dans la console. L'intégration mail
 seront également désactivées.
 
 En production, il est recommandé de ne pas utiliser SQLite pour des raisons de performances.
