Customize the network configurable parameters.
The directory ruby/catapult-templates/peer_node/resources of the Catapult Service Bootstrap repository comes with a set of files to configure the network.
The .properties files provided can be edited with any text editor before launching a network for the first time.
Find below the list of configurable properties.
