Correct Installation Steps for RT-AC1300UHP (Ver: B1)

Hi, can I have some guidance to safely get OpenWRT setup into this router?
It is currently running default stock firmware of AsusWrt.

The guide says I would need to use serial cable on step 2, I do not have serial a cable.

There is a subsection called "Easy Installation" is it possible to just follow that method instead?

Don't own the device, but that's what I would have done.
