 A secret variable can be used in a script or MDM configuration profile by specifying the variable name in the format `$FLEET_SECRET_MYNAME` or `${FLEET_SECRET_MYNAME}`. When the script or profile is sent to the host, Fleet will replace the variable with the actual secret value. The prefix `FLEET_SECRET_` is required to indicate that the variable is a secret, and Fleet reserves this prefix for secret variables.
 
+For macOS and Linux scripts, if a secret doesn't have the `$FLEET_SECRET_` prefix, it will be treated as a local environment variable.

-Fleet supports adding [GitHub environment variables](https://docs.github.com/en/actions/learn-github-actions/variables#defining-environment-variables-for-a-single-workflow) in your configuration profiles. Use `$ENV_VARIABLE` format. Variables beginning with `$FLEET_VAR_` are reserved for Fleet server. The server will replace these variables with the actual values when profiles are sent to hosts.

 Use `labels_include_all` to target hosts that have all labels in the array, `labels_include_any` to target hosts that have any label in the array, or `labels_exclude_any` to target hosts that don't have any of the labels in the array. Only one of `labels_include_all`, `labels_include_any`, or `labels_exclude_any` can be specified. If none are specified, all hosts are targeted.
