 == Frequently Asked Questions ==
 
-== Can I use this plugin with the new editor (aka Gutenberg) / WordPress 5.0 and above? ==
+== Can I use this plugin with the new block editor (aka Gutenberg) / WordPress 5.0 and above? ==
 
-The new editor (Gutenberg) removes the custom fields meta box and, as a result, you are unable to add or edit existing code embeds. However, the plugin will continue to work, in all other ways.
+Yes, you can. By default, custom fields are hidden inside the block editor but can be revealed.
 
-However, a rather smart plugin named [Custom Fields for Gutenberg](https://wordpress.org/plugins/custom-fields-gutenberg/) will add this functionality back in - with that active, you can happily continue to use this plugin, even with WordPress 5.0 or later.
