-= Using a user-defined certificate and key
+= Adding an external certificate authority key and certificate
 
 By default, {SMProductName} generates a self-signed root certificate and key and uses them to sign the workload certificates. You can also use the user-defined certificate and key to sign workload certificates with user-defined root certificate. This task demonstrates an example to plug certificates and key into {SMProductShortName}.
