    protected defaultOptions = {
        // Fill these out if you want defaults for anything
    }

    protected async _init() {
        // Do initialization logic here, will be called before anything else is run.
    }

    protected async _start() {
        // Do stuff here. Gets called inside of `service.start()`.
    }
