<1> Specify the block device of the system to install to.
<2> Specify the URL of the RAW image that you uploaded to your server.
<3> Specify the URL of the Ignition config file for this machine type.

<4> Set `ip=dhcp` or set an individual static IP address (`ip=`) and DNS server (`nameserver=`) on each node.
For example, setting
`ip=10.10.10.2::10.10.10.254:255.255.255.0:core0.example.com:enp1s0:none nameserver=4.4.4.41` sets:
* Node's IP address to 10.10.10.2
* Gateway address to 10.10.10.254
* Netmask to 255.255.255.0
* Hostname to core0.example.com
* The DNS server address to 4.4.4.41
* Node's IP address to `10.10.10.2`
* Gateway address to `10.10.10.254`
* Netmask to `255.255.255.0`
* Hostname to `core0.example.com`
* The DNS server address to `4.4.4.41`
<5> If you use multiple network interfaces or DNS servers, you can further customize the IP address configuration in the following ways:
* If your system has multiple network interfaces, you can add multiple IP address configurations by specifying multiple `ip=` entries.
* If your system has multiple network interfaces, you can use a combination of DHCP and static IP configurations. You must specify the interface to use, for example `ip=enp1s0:dhcp ip=10.10.10.2::10.10.10.254:255.255.255.0:core0.example.com:enp2s0:none`.
* You can provide multiple DNS servers by adding a `nameserver=` entry for each server, such as `nameserver=1.1.1.1 nameserver=8.8.8.8`.
. Press Enter to complete the installation. After {op-system} installs, the system
reboots. After the system reboots, it applies the Ignition config file that you
