+In order to use a reference to a generic component in a `ref` you need to use the [`vue-component-type-helpers`](https://www.npmjs.com/package/vue-component-type-helpers) library as `InstanceType` won't work.
+
+```vue
+<script
+  setup
+  lang="ts"
+>
+import componentWithoutGenerics from '../component-without-generics.vue';
+import genericComponent from '../generic-component.vue';
+
+import type { ComponentExposed } from 'vue-component-type-helpers';
+
+// Works for a component without generics
+ref<InstanceType<typeof componentWithoutGenerics>>();
+
+ref<ComponentExposed<typeof genericComponent>>();
+```

 ## Restrictions {#restrictions}
 
 - Due to the difference in module execution semantics, code inside `<script setup>` relies on the context of an SFC. When moved into external `.js` or `.ts` files, it may lead to confusion for both developers and tools. Therefore, **`<script setup>`** cannot be used with the `src` attribute.
