+# Purpose
+
+Clustered S3 storage provider.
+
+# Notes
+
+Considering moving to the [operator](https://github.com/rajsinghtech/garage-operator), but currently deploys as chart.
+
+Backing storage comes from [iSCSI](https://docs.alexlebens.dev/applications/democratic-csi-synology-iscsi/).
+
+Primary endpoint for most S3 targets, alongside PiBox and Digital Ocean.
+
+[Rclone](https://docs.alexlebens.dev/applications/rclone/) handles any kind of syncing to the other endpoints as needed.
