Hello, hope everyone is doing well.
I am wanting to do a clean install of Ventura on a M1 MacBook Air.
I created the bootable usb ventura installer.
I am just wanting to know if these are the steps to take, as I never did a full format and install on an Apple Silicon Mac.

Start the MacBook pressing the power until I get to the boot options.
Select disk utility and erase the SSD.
Boot to the USB installer and then install Ventura to the previously erased SSD.

Is this basically it? Or I am missing some step?

Some sites I saw online mention that before going to boot options, the contents of the Mac should first be erased from the system settings with the option to “erase all content and settings”.

Is that necessary?

Thank you for your help.
Best regards.

It's not that simple. You have to log out of your account completely. Do a complete reset to delete all content and settings. In case something goes wrong, you need a second mac to install the system, because the M1 installs the system in DFU mode
