 # Setting up Machine Configuration
 
 # Introduction
-Machine configuration operation is used to configure [Red Hat Enterprise Linux CoreOS (RHCOS)](https://docs.openshift.com/container-platform/4.12/architecture/architecture-rhcos.html) on each node in a RHOCP cluster.
+Machine configuration operation is used to configure [Red Hat Enterprise Linux CoreOS (RHCOS)](https://docs.openshift.com/container-platform/4.13/architecture/architecture-rhcos.html) on each node in a RHOCP cluster.
 
 [Machine config operator](https://github.com/openshift/machine-config-operator) (MCO) is provided by Red Hat to manage the operating system and machine configuration. In this project through the MCO, cluster administrators can configure and update the kernel to provision Intel Hardware features on the worker nodes.
 
-MCO is one of the technologies used in this project to manage the machine configuration. In current OCP-4.12, MCO might reboot the node to enable the machine configuration. Since rebooting the node is undesirable, alternative machine configuration technologies are under investigation. For more details, see this [issue](https://github.com/intel/intel-technology-enabling-for-openshift/issues/34).

 The best approach is to work with the RHCOS team to push the RHCOS configuration as the default configuration for a RHOCP cluster on [Day 0](https://www.ibm.com/cloud/architecture/content/course/red-hat-openshift-container-platform-day-2-ops/).
