 ## Examples
 
+### A Module Level Trigger application
+
+This MLT application plot is taken from the `local-1x1-config` in the daqsystemtest repo (as of Nov-6-2024). Notice that the `DataSubscriberModule` instance would receive, among other `tcs_.*` messages received over the network, `tcs_random-tc-generator` messages sent by the `RandomTCMakerModule` instance in the same application:

+### A full Session
+
+This is the full session associated with the `local-1x1-config` in the daqsystemtest repo. Notice here you can see the loopback effect for the MLT application described above:
