The link you shared literally has the following content:

Title "Get Started"

First card "Root your TV"

Description "Jailbreak your TV and install Homebrew Channel. Gain more control over your TV"

So, to install Homebrew Channel, as your comment instructs, I'd first need to root my TV. No way are any non devs capable of that.

Re-read the link you've shared.

The comment that I suggested you re-read was the one where I explained that you can install Kodi from Homebrew Channel via developer mode without rooting your TV.

And the link I provided very clearly and explicitly documents both methods: rooting and dev mode.
