Configure touchscreen dashboard?

I’m super confused on how to have a touchscreen that corresponds with the home assistant. I bought the official 7" raspberry pi touch screen and connected it to my raspberry. When I start my raspberry pi it shows the terminal of all the files being loaded. How do I have it display the dashboard of my home assistant instead? Do I need another raspberry pi connected to the touchscreen and pull a browser for it?

If you are using Home Assistant OS instead of Home Assistant Supervised, yes you do.

thanks for the reply.

Since I’m using the HA OS, what is the best way to pull up the specific dashboard to make it look clean?

Design a dashboard specifically for the small sized display and set it as default on the device.
