MQTT topics?

I’m using the MQTT Publisher plugin to send telemetry data to home assistant. I can’t find any documentation on the topic structure from simhub. 

I have the plugin installed in simhub and can successfully connect to Mosquitto on Home Assistant.

But I can’t get telemetry data. I think I don’t have the topics properly configured, but I can’t find any documentation on them.

Has anyone successfully navigated this?
