Mosquitto configuration

Hello I have installed mosquitto on hassbian using sudo hassbian-config install mosquitto.

How to config HASS to use it as its broker?

The old broker that came bundled with Home Assistant has been deprecated and should not be used. You are correct that you should install something outside of home assistant.

Are you aware of the fact that hassbian will no longer be continued:
