Howto install insteon component

Please forgive my newbieness. I just installed hass.io on my pi0 w. I see Insteon in https://www.home-assistant.io/components/ but I don’t see it in the add-on store. I would like to install this component. Could someone please help me.

Responding to my own post for others to find.
I now understand that the components in https://www.home-assistant.io/components/ are pre-installed and only need to be added to the configuration.yaml to be invoked.
