 == Choosing a method to install {product-title} on bare metal
 
-You can install {product-title} on installer-provisioned or user-provisioned infrastructure. The default installation type uses installer-provisioned infrastructure, where the installation program provisions the underlying infrastructure for the cluster. You can also install {product-title} on infrastructure that you provision. If you do not use infrastructure that the installation program provisions, you must manage and maintain the cluster resources yourself.
+The {product-title} installation program offers four methods for deploying a cluster:
+
+* *Interactive*: You can deploy a cluster with the web-based link:https://access.redhat.com/documentation/en-us/assisted_installer_for_openshift_container_platform/2022/html-single/assisted_installer_for_openshift_container_platform/index[{ai-full}]. This is the recommended approach for clusters with networks connected to the internet. The {ai-full} is the easiest way to install {product-title}, it provides smart defaults, and it performs pre-flight validations before installing the cluster. It also provides a RESTful API for automation and advanced configuration scenarios.
+
+* *Local Agent-based*: You can deploy a cluster locally with the xref:../../installing/installing_with_agent_based_installer/preparing-to-install-with-agent-based-installer.adoc#preparing-to-install-with-agent-based-installer[agent-based installer] for air-gapped or restricted networks. It provides many of the benefits of the {ai-full}, but you must download and configure the link:https://console.redhat.com/openshift/install/metal/agent-based[agent-based installer] first. Configuration is done with a commandline interface. This approach is ideal for air-gapped or restricted networks.
+
+* *Automated*: You can xref:../../installing/installing_bare_metal_ipi/ipi-install-overview.adoc#ipi-install-overview[deploy a cluster on installer-provisioned infrastructure] and the cluster it maintains. The installer uses each cluster host's baseboard management controller (BMC) for provisioning. You can deploy clusters with both connected or air-gapped or restricted networks.
+
+* *Full control*: You can deploy a cluster on xref:../../installing/installing_bare_metal/installing-bare-metal.adoc#installing-bare-metal[infrastructure that you prepare and maintain], which provides maximum customizability. You can deploy clusters with both connected or air-gapped or restricted networks.
+
+The clusters have the following characteristics:
+
+* Highly available infrastructure with no single points of failure is available by default.
+* Administrators maintain control over what updates are applied and when.
 
 See xref:../../architecture/architecture-installation.adoc#installation-process_architecture-installation[Installation process] for more information about installer-provisioned and user-provisioned installation processes.

+In {product-title} version {product-version}, you can install a cluster on your Nutanix instance with two methods:

+You can use the installation program to deploy each type of cluster. The installation program generates main assets such as Ignition config files for the bootstrap, control plane (master), and worker machines. You can start an {product-title} cluster with these three configurations and correctly configured infrastructure.
 
 The {product-title} installation program uses a set of targets and dependencies to manage cluster installations. The installation program has a set of targets that it must achieve, and each target has a set of dependencies. Because each target is only concerned with its own dependencies, the installation program can act to achieve multiple targets in parallel with the ultimate target being a running cluster. The installation program recognizes and uses existing components instead of running commands to create them again because the program meets dependencies.
