Matt, for an initial install should I follow the steps at the start of this thread or the Wiki?

They're complementary - the OP specifies the steps needed for each type of install, the details of which are listed in the OP (for script functions) and the wiki (for hardware and post-install steps)

Thanks. Can you confirm my understanding.

I would do this:

For a standalone setup, you will need to perform the following steps:

Open the ChromeBox and remove the write-protect screw
Put the ChromeBox in developer mode
Download/run the EZ setup script
Select the Standalone / coreboot Install option, which will backup your stock firmware/BIOS and flash a custom one
Create install media for desired OS. Script includes option to create install media for OpenELEC and Kodibuntu
Power off ChromeBox
Connect/plug-in USB install media
Power on ChromeBox, Press [ESC] from boot menu, select USB device
Install OpenELEC, Kodibuntu, or your OS of choice

I would than follow the steps listed beneath:

-------------------------------------------
Using the Kodi EZ Setup Script

(Step 7)

Lastly, check your recommended settings, 3.4 Recommended Settings via the wiki page.
