 The `groupId` must match the value specified in the implementation of the `CodeVisionProvider`; if not specified, it defaults to the `id`.
 The `groupName` is the name shown in the code vision group, and the `description` will be visible in the right details panel.
 
+Code vision preview is available under <ui-path>Settings | Editor | Inlay Hints | Code vision</ui-path>.
+In case if multiple preview examples in different languages are provided for an existing code vision provider, IDE will choose the most important from its point of view.
+For example, IntelliJ IDEA will use Java preview, PhpStorm will use PHP preview, etc.
+
+To provide a preview example for a custom code vision provider:
+1. Create a <path>codeVisionProviders/\$model_id\$/preview.\$ext\$</path> file, for example, <path>codeVisionProviders/vcs.code.vision/preview.java</path>.
+   The <path>\$modelId\$</path> must match the `groupId` of `CodeVisionGroupSettingProvider` and `modelId` (see 2.).
+2. Register an `com.intellij.codeInsight.codeVisionSettingsPreviewLanguage`, which specifies the preview `language` and `modelId`.

 **Examples:**
 - [`JavaInheritorsCodeVisionProvider`](%gh-ic%/java/java-impl/src/com/intellij/codeInsight/daemon/impl/JavaInheritorsCodeVisionProvider.kt) - shows number of Java class or method inheritors. Clicking the inlay hint opens the list of inheritors. This provider is `DaemonBoundCodeVisionProvider`.
 - [`JavaReferencesCodeVisionProvider`](%gh-ic%/java/java-impl/src/com/intellij/codeInsight/daemon/impl/JavaReferencesCodeVisionProvider.kt) - shows number of usages of Java class or member. Clicking the inlay opens the list of usages or navigates to the usage if only one exists. This provider is `DaemonBoundCodeVisionProvider`.
