 In the Azure Identity client libraries, choose one of the following approaches:
 
-- Use `DefaultAzureCredential`, which will attempt to use the `WorkloadIdentityCredential`.
+- Use `DefaultAzureCredential`, which will attempt to use the `WorkloadIdentityCredential`. †
 - Create a `ChainedTokenCredential` instance that includes `WorkloadIdentityCredential`.
 - Use `WorkloadIdentityCredential` directly.
 
 The following table provides the **minimum** package version required for each language's client library.
