+Content and media types always have the 'delete missing' feature available. Enabling this setting turns the 'delete missing' feature on for additional [EntityTypes](https://github.com/umbraco/Umbraco-CMS/blob/contrib/src/Umbraco.Core/Constants-UdiEntityType.cs) for the Umbraco objects. When pushing these extra objects, uSync will delete orphaned items. 
+
+As with a lot of settings that permit automatic deleting, enabling this can badly break your site, and we reccomend you do not enable it unless you're sure about the potential consequences.
