   Generate and publish an SDK to a package registry and/or source repository
 
   Generate and publish an SDK using a publishing profile configured in the APIMatic App. Requires an input directory
-  containing the API specification. Run it with no flags, or with only --git-init, for guided mode, or pass flags for
-  CI/CD. When you pass flags, --profile-id, --language, --version, and --publish-type are required.
+  containing the API specification. Run it with no flags, or with only --git-init or --auth-key, for guided mode, or
+  pass flags for CI/CD. When you pass flags, --profile-id, --language, --version, and --publish-type are required.
   Your changes to the SDK are merged before it is published, as sdk generate does with git 2.38 or later: with flags,
   always; in guided mode, add --git-init. Nothing is published while conflicts are left to resolve.
