 > [!IMPORTANT]
 > You may not need this plugin. It was developed long before Sanity had fully-featured [live preview, visual editing](https://www.sanity.io/docs/visual-editing/introduction-to-visual-editing), [perspectives](https://www.sanity.io/docs/content-lake/perspectives) and [content releases](https://www.sanity.io/docs/user-guides/content-releases) which are more seamless ways to stage and preview content before publishing into production. It is recommended you investigate these features first before using this plugin.
