-In {product-title} version {product-version}, you can install a customized
-cluster on infrastructure that the installation program provisions on
-Google Cloud Platform (GCP). To customize the installation, you modify
-parameters in the `install-config.yaml` file before you install the cluster.
+In {product-title} version {product-version}, you can install a cluster on {gcp-first} by using installer-provisioned infrastructure with customizations, including network configuration options. In each, you modify parameters in the `install-config.yaml` file before you install the cluster.
+
+By customizing your network configuration, your cluster can coexist with existing IP address allocations in your environment and integrate with existing MTU and VXLAN configurations.
+
+You must set most of the network configuration parameters during installation, and you can modify only `kubeProxy` configuration parameters in a running cluster.
