  [NOTE]
  ====
  The `99-worker-custom.bu` file is set to create a machine config for worker nodes. To deploy on control plane nodes, change the role from `worker` to `master`. To do both, you could repeat the whole procedure using different file names for the two types of deployments.
  ====
  
  . Create a `MachineConfig` object by giving Butane the file that you created in the previous step:

  [source,terminal]
  ----
  $ butane 99-worker-custom.bu -o ./99-worker-custom.yaml

  A `MachineConfig` object YAML file is created for you to finish configuring your machines.
