+# Purpose   : This confguration is a blueprint for a radio-only node.
+#             It uses Mercury as the radio interface. If a supported
+#             et-lora device is detected, it will be enabled, too.

+  # If you enable Transport, your system will route traffic
+  # for other peers, pass announces and serve path requests.
+  # This should only be done for systems that are suited to
+  # act as transport nodes, ie. if they are stationary and
+  # always-on. This directive is optional and can be removed
+  # for brevity.

+  # By default, the first program to launch the Reticulum

+  # programs can communicate with. Only the shared instance
+  # opens all the configured interfaces directly, and other
+  # local programs communicate with the shared instance over
+  # a local socket. This is completely transparent to the
+  # user, and should generally be turned on. This directive
