Why changing this line number? I think markdown rendering is smart enough to follow the numbers, but from the edition point of view that's weird 😉 (1, 2, 3, 5, 6 where's the 4? :D)

	1. Create a dedicated directory on the Nebraska server to store the packages: `/PATH/TO/STORE/PACKAGES`
	2. You can find the official packages here: https://update.release.flatcar-linux.net
	3. Download/Upload the packages you want to server to that folder: `wget -o- https://update.release.flatcar-linux.net/{{architecture}}-usr/{{version}}/flatcar_production_update.gz` or alternatively `cp /media/usb/flatcar_production_update.gz /PATH/TO/STORE/PACKAGES/`.
	5. Start your nebraska instance with the following options `nebraska -host-flatcar-packages=true -flatcar-packages-path=/PATH/TO/STORE/PACKAGES -nebraska-url=http://your.Nebraska.host:port`
	6. Register the new package in Nebraska too. Go to your application > Add Package > Fill the form, where the `URL` and the `filename` should match with the options you provided earlier
