 First step is to create  a SecretClient.
 
-<!-- @insert_snippet: SecretSample1CreateCredential -->
 ```cpp
-  auto credential = std::make_shared<Azure::Identity::DefaultAzureCredential>();
+auto credential = std::make_shared<Azure::Identity::DefaultAzureCredential>();

 ### Create a secret
 
 We call the secret client to create a secret.
 
-<!-- @insert_snippet: SecretSample1CreateSecret -->
 ```cpp
-    std::string secretName("MySampleSecret");
-    std::string secretValue("my secret value");

 We retrieve a secret by name.
