-You can install {product-title} on on-premise hardware or on-premise VMs using the {ai-full} (AI). AI provides you with more options for customization than an installer-provisioned installation, while still running pre-flight validations and using smart defaults.

+= Using the Assisted Installer
+
+The {product-title} link:https://console.redhat.com/openshift/assisted-installer/clusters/~new[{ai-full}] is a user-friendly installation solution offered on the link:http://console.redhat.com[Red Hat Hybrid Cloud Console]. The {ai-full} supports the various deployment platforms with a focus on bare metal and vSphere infrastructures.
+
+The {ai-full} provides installation functionality as a service. This software-as-a-service (SaaS) approach has the following advantages:
+
+* *Web user interface:* The web user interface performs cluster installation without the user having to create the installation configuration files manually.
+* *No bootstrap node:* A bootstrap node is not required when installing with the {ai-full}. The bootstrapping process executes on a node within the cluster.
+* *Hosting:* The {ai-full} hosts:
+  - Ignition files
+  - The installation configuration
+  - A discovery ISO
+  - The installer
+* *Streamlined installation workflow:* Deployment does not require in-depth knowledge of {product-title}. The {ai-full} provides reasonable defaults and provides the installer as a service, which:
+  - Eliminates the need to install and run the {product-title} installer locally.
+  - Ensures the latest version of the installer up to the latest tested z-stream releases. Older versions remain available, if needed.
+  - Enables building automation by using the API without the need to run the {product-title} installer locally.
+* *Advanced networking:* The {ai-full} supports IPv4/IPv6 dual stack networking, NMState-based static IP addressing, and an HTTP/S proxy.
+* *Pre-installation validation:* The {ai-full} validates the configuration before installation to ensure a high probability of success. Validation includes:
+  - Ensuring network connectivity
+  - Ensuring sufficient network bandwidth
+  - Ensuring connectivity to the registry
+  - Ensuring time synchronization between cluster nodes
+  - Verifying that the cluster nodes meet the minimum hardware requirements
+  - Validating the installation configuration parameters
+* *REST API:* The {ai-full} has a REST API, enabling automation.
+
+The {ai-full} supports installing {product-title} on premises in a connected environment, including with an optional HTTP/S proxy. It can install the following:
+
+* Highly available {product-title} or Single Node OpenShift (SNO)
+* {product-title} on bare metal or vSphere with full platform integration, or other virtualization platforms without integration
+* Optionally {VirtProductName} and {rh-storage} (formerly OpenShift Container Storage)
+
+The user interface provides an intuitive interactive workflow where automation does not exist or is not required. Users may also automate installations using the REST API.
+
+See link:https://console.redhat.com/openshift/assisted-installer/clusters/~new[Install OpenShift with the Assisted Installer] to create an {product-title} cluster with the {ai-full}.
