Page builder in Core

Which is the proper way to set page builder up in a core site. the documentation shows these tags@Html.Kentico().PageBuilderStyles() @Html.Kentico().PageBuilderScripts() @Html.Kentico().EditableArea(@area1@) but the dancing goat template has these( with similarly written script and css tags)@editable-area area-identifier=@area1@ area-options-allowed-widgets=@AreaRestrictionHelper.GetHomePageRestrictions()@ allow-widget-output-cache=@true@ widget-output-cache-expires-after=@TimeSpan.FromMinutes(5)@ /@ is there a proper way, and where in the documentation (if it is in there) can I find info on the second way that dancing goat uses?
