-Domain Name Service (DNS) is a technique for storing network node names throughout a network. This articles maps a domain to your spring app, such as [www.contoso.com](https://www.contoso.com/), using a CNAME record. It secures the custom domain with a certificate and shows how to enforce Transport Layer Security (TLS), also known as Secure Sockets Layer (SSL).
+ This article shows how to map a custom web site domain, such as such as [www.contoso.com](https://www.contoso.com/), to your app in Azure Spring Apps. This mapping is accomplished by using a CNAME record that is made known to the Domain Name Service (DNS) that stores node names throughout the network.
 
-# Prerequisites
-* An application deployed to Azure Spring Apps (see Quickstart: Launch an existing application in Azure Spring Apps using the Azure portal, or use an existing app).
-* A domain name with access to the DNS registry for domain provider such as GoDaddy.
-* A certificate resource created under Azure Container App Environment (see [Add certificate in Container App](https://learn.microsoft.com/en-us/azure/container-apps/custom-domains-certificates))

+## Prerequisites
+
+* An application deployed to Azure Spring Apps. For more information see [Quickstart: Build and deploy apps to Azure Spring Apps](/azure/spring-apps/quickstart-deploy-apps).
+* A domain name registered in the DNS registry as provided by a web hosting or domain provider.
+* A certificate resource created under the Azure Container Apps Environment, see [Add certificate in Container App](/azure/container-apps/custom-domains-certificates).
+
+## Map a custom domain
+
+To map the custom domain, you create the CNAME record and then use the Azure CLI to bind the domain to an app in Azure Spring Apps.
 
 ## Create the CNAME record
 
-* Go to your DNS provider and add a CNAME record to map your domain to the fqdn of your spring app. 
-* Add an TXT record with then name asuid.{subdomain}, and the value of the TXT record is the custom domain verification id of your container app managed environment. You can find this value using: 
+* Contact your DNS provider to request a CNAME record to map your domain to the Full Qualified Domain Name (FQDN) of your spring app.
+* Add a TXT record with the name `asuid.{subdomain}`, with the value being the verification ID of your Azure Container Apps Environment. You can find this value using the following command.
 
 ```azurecli
