-### Dependency Scoping
-
-By default the action will only fail on `runtime` dependencies that have vulnerabilities or unacceptable licenses, ignoring `development` dependencies. You can override this behavior with the `fail-on-scopes` option, which will allow you to list the specific dependency scopes you care about. The possible values are: `unknown`, `runtime`, and `development`. Note: Filtering by scope will not be supported on Enterprise Server just yet, as the REST API's introduction of `scope` will be released in an upcoming Enterprise Server version. We will treat all dependencies on Enterprise Server as having a `runtime` scope and thus will not be filtered away.
