 # Setting up External DNS with Contour
 
-This tutorial describes how to configure External DNS to use either the Contour `IngressRoute` or `HTTPProxy` source.
+This tutorial describes how to configure External DNS to use the Contour `HTTPProxy` source.
-The `IngressRoute` CRD is deprecated but still in-use in many clusters however it's recommended that you migrate to the `HTTPProxy` resource.
 Using the `HTTPProxy` resource with External DNS requires Contour version 1.5 or greater.
 
 ### Example manifests for External DNS
 #### Without RBAC
-Note that you don't need to enable both of the sources and if you don't enable `contour-ingressroute` you also don't need to configure the `contour-load-balancer` setting.
