HomeAssistant on Raspberry Pi

I have installed HomeAssistant on my Raspberry Pi.
It’s working fine, but I understood that I have to update the Raspberry Pi from time to time, but I have no idea how I can access the Raspberry Pi in order to come at the command prompt to update it.
I hope anybody can give me some help.
Thank you.

If you’re using Home Assistant OS then you don’t have to worry about it, it’s all handled through the UI.

Ok, thank you very much.
