 == Using MachineConfig objects to configure nodes
 
-You can use the tasks in this section to create `MachineConfig` objects that modify files, systemd unit files, and other operating system features running on {product-title} nodes. For more ideas on working with machine configs, see content related to link:https://access.redhat.com/solutions/4510281[updating] SSH authorized keys, link:https://access.redhat.com/verify-images-ocp4[verifying image signatures], link:https://access.redhat.com/solutions/4727321[enabling SCTP], and link:https://access.redhat.com/solutions/5170251[configuring iSCSI initiatornames] for {product-title}.

 {product-title} supports link:https://coreos.github.io/ignition/configuration-v3_2/[Ignition specification version 3.2]. All new machine configs you create going forward should be based on Ignition specification version 3.2. If you are upgrading your {product-title} cluster, any existing Ignition specification version 2.x machine configs will be translated automatically to specification version 3.2.
