 === Customizing the Hostname for the {project_name} Server
 
-The hostname SPI introduced a flexible way to configure the hostname for the {project_name} server. There are two built-in providers. The first is `request`, which uses the request headers to determine the hostname. This is the *default setting* for {project_openshift_product_name} image. The second is `fixed`, which allows configuring a fixed hostname. The latter makes sure that only valid hostnames can be used and allows internal applications to invoke {project_name} server through an alternative URL.
+The hostname SPI introduced a flexible way to configure the hostname for the {project_name} server.
+The default hostname provider one is `default`. This provider provides enhanced functionality over the original `request` provider which is now deprecated. Without additional settings, it uses the request headers to determine the hostname similarly to the original `request` provider.
+
+For configuration options of the `default` provider, refer to the {installguide_link}#_hostname[{installguide_name}].
+The `frontendUrl` option can be configured via `SSO_FRONTEND_URL` environment variable.
+
+[NOTE]
+For backward compatibility, `SSO_FRONTEND_URL` settings is ignored if `SSO_HOSTNAME` is also set.
+
+Another option of hostname provider is `fixed`, which allows configuring a fixed hostname. The latter makes sure that only valid hostnames can be used and allows internal applications to invoke the {project_name} server through an alternative URL.
 
 Run the following commands to set the `fixed` hostname SPI provider for the {project_name} server:
