Resetting iMac to factory

[NickTB]

As above, my new iMac has arrived and I have no idea how to reset it back to factory. I have deauthorised iTunes, but I need to remove all traces of me from the machine. Can anyone help?

Thanks,
Nick

Restart your Mac in recovery mode (Command + R during start up)
Use disk utility to erase the hard drive
Reinstall MacOS
