 ## AWS
 
 The `aws` module shows the current AWS region and profile when
-credentials or a `credential_process` have been setup. This is based on
+credentials, a `credential_process` or a `sso_start_url` have been setup. This is based on
 `AWS_REGION`, `AWS_DEFAULT_REGION`, and `AWS_PROFILE` env var with
 `~/.aws/config` file. This module also shows an expiration timer when using temporary
 credentials.
