 ## Before You Customize
 
-Before customizing generated code, consider whether your change should be made in TypeSpec (`client.tsp`) instead. TypeSpec customizations are cleaner and survive regeneration. See the [TypeSpec Client Customizations Reference](https://github.com/Azure/azure-sdk-tools/blob/main/eng/common/knowledge/customizing-client-tsp.md) for available decorators like `@@clientName`, `@@access`, etc.
+Before customizing generated code, consider whether your change should be made in TypeSpec (`client.tsp`) instead. TypeSpec customizations allow you to apply changes to multiple languages at once, are more discoverable for other languages, and live right near the spec bringing us more to a single source of truth. See the [TypeSpec Client Customizations Reference](https://github.com/Azure/azure-sdk-tools/blob/main/eng/common/knowledge/customizing-client-tsp.md) for available decorators like `@@clientName`, `@@access`, etc.
 
 Use C# code customizations (partial classes) when TypeSpec cannot express the behavior you need.
