 # This is a helper script for adding more peers to an already
 # running tezos-node. It first queries for, and adds all
 # foundation nodes, then queries tzscan's API for more peers and
 # adds them as well.
+# 
 #
 # The tezos-admin-client binary will output 'Error' messages in
 # most cases, even when already connected to a peer.
 #
 # Be sure to install jq and configure the TZPATH variable below
 # [yum|apt] install jq
