I am getting ready to do a clean install of Big Sur. Trying to do an erase, but I am confused by what I see in "Disk Utility". I see Macintosh HD and Macintosh HD Data. Which volume do I erase then do a clean install of Big Sur. Looking at the communities, I am not seeing a good explanation of which volume to erase then install Big Sur. Is there a reference or can someone give me a more complete explanation?

Disk Utility>View>Show All Devices

if you are doing a clean install you erase/format the parent Drive— top of the device tree; Not the Container level, not the Volume level.
