Under the 'Generating Message from MycroftSkill' code tab. Change self.emitter.emit to self.bus.emit in the docs. Very confusing to try to get working..

Thanks auwsom!

I've updated the method to the new self.bus.emit and extended the examples to show what needs to be imported: https://mycroft-ai.gitbook.io/docs/mycroft-technologies/mycroft-core/message-bus#mycroftskill-interaction
