+Le principe est de synchroniser un dossier avec un volume s3.
+
+Voici le fonctionnement :
+- la commande prend comme paramètre le dossier source `/data/` et un bucket S3 `s3://bucket`
+- il synchronise le bucket avec le dossier puis lance `inotify` pour resynchroniser le bucket dès qu'un évènement se produit dans le dossier (modification, création, suppression)
+
+Inspiration : [docker-s3-volume](https://github.com/elementar/docker-s3-volume)
+
+## README original
 
 Creates a Docker container that is restored and backed up to a directory on s3.
 You could use this to run short lived processes that work with and persist data to and from S3.
