Trying to connect Hubitat to Indigo

Trying to install/configure a new Hubitat into Indigo. I've installed the plugins; Hubitat Bridge, MQTT Broker and MQTT Connector.
I'm stuck at how to get MQTT installed or connected to the Hubitat. I've been to the plugin page but still confused as there is an assumption (I think) that this connection has already been made. OR.... a link to the directions that walk you through this for MQTT and Hubitat.

Thanks

This would probably be better in the Hubitat forum. viewforum.php?f=353

I know nothing about Hubitat.

I'll post there
