+#### `.broadcast(eventObject, payload)`
 
 Calls the xstate `.send()` method on every running interpreter in the hierarchy. This is especially useful to avoid the use of the `autoforward` option on all of your invoked child machines.
 
-- `eventName` is a string event to be sent
 - `eventObject` is an object with a `type` property of the event name, along with other optional fields
 - `payload` is an object of optional fields to be added to the event object
