+### Download snapshots for elasticsearch and the wallet server (optional)
+
+You can skip the initial sync by starting from a snapshot. The following will download a snapshot of the elasticsearch volume and move it into the default location for docker volumes on ubuntu, on other systems you may need to adjust the path used here. Note: snapshot heights must be the same. The tars can be deleted after setting the volumes up.
