 Plugins can register settings, that PeerTube will inject in the administration interface.
+The following fields will be automatically translated using the plugin translation files: `label`, `html`, `descriptionHTML`, `options.label`.
+**These fields are injected in the plugin settings page as HTML, so pay attention to your translation files.**
 
 Example:
 
 ```js
-registerSetting({
-  name: 'admin-name',
