 `aws-sso-util configure populate` allows you to configure profiles for all the access you have through AWS SSO.
 You specify one or more regions, and a profile is created for every account, role, and region you have access to through AWS SSO (note that if access to a region is prohibited by an IAM policy, this does not suppress creation of the profile).
 
+## Options

 You can provide regions through the `--region`/`-r` flag (multiple regions like `-r REGION1 -r REGION2`), or by setting the `AWS_CONFIGURE_DEFAULT_REGION` environment variable (this is ignored if any regions are specified on the command line).
 
 You can view the profiles without writing them using the `--dry-run` flag.
