+# Serveur de synchronisation de Firefox pour Yunohost

+[![Install ffsync with YunoHost](https://install-app.yunohost.org/install-with-yunohost.png)](https://install-app.yunohost.org/?app=ffsync)
+
+*[Read this readme in english.](./README.md)*
+> *Ce package vous permet d'installer ffsync rapidement et simplement sur un serveur Yunohost.   
+Si vous n'avez pas YunoHost, regardez [ici](https://yunohost.org/#/install) pour savoir comment l'installer et en profiter.*
+
+## Vue d'ensemble
+
+Le serveur de synchronisation permet un remplacement du serveur par défaut de Firefox (hébergé par Mozilla).
+
+Par défaut, le serveur reporte l'authentification aux serveurs de comptes de Mozilla à https://accounts.firefox.com. vous vous authentifierez donc sur les serveurs de Mozilla, mais _le stockage de vos informations se fera sur votre serveur_.
+
+**Version incluse :** 1.9.1

+## Documentation
+
+ * Documentation officialle : https://docs.services.mozilla.com/howtos/run-sync-1.5.html
+ * Documentation YunoHost : https://yunohost.org/#/app_ffsync
+
+## Configuration
+
+Une fois installé, la page `http://domain.tld/path` vous explique comment l'utiliser.
