+## :book: Rule Details
+
+Vue 3.5 introduced a new way of obtaining template refs via
+the [`useTemplateRef()`](https://vuejs.org/guide/essentials/template-refs.html#accessing-the-refs) API.
+
+This rule enforces using the new `useTemplateRef` function instead of `ref` for template refs.
+
+<eslint-code-block :rules="{'vue/prefer-use-template-ref': ['error']}">
+
+```vue
+<template>
+  <button ref="submitRef">Submit</button>
+  <button ref="closeRef">Close</button>
+</template>
+
+<script setup>
+  import { ref, useTemplateRef } from 'vue';
+
+  /* ✓ GOOD */
+  const submitRef = useTemplateRef('submitRef');
+  const submitButton = useTemplateRef('submitRef');
+  const closeButton = useTemplateRef('closeRef');
+
+  /* ✗ BAD */
+  const closeRef = ref();
+</script>
+```
+
+</eslint-code-block>
+
+This rule skips `ref` template function refs as these should be used to allow custom implementation of storing `ref`. If you prefer
+`useTemplateRef`, you have to change the value of the template `ref` to a string.
+
+<eslint-code-block :rules="{'vue/prefer-use-template-ref': ['error']}">
+
+```vue
+<template>
+  <button :ref="ref => button = ref">Content</button>
+</template>
+
+<script setup>
+  import { ref } from 'vue';
+
+  /* ✓ GOOD */
+  const button = ref();
+</script>
+```
+
+</eslint-code-block>
+
+## :wrench: Options
+
+Nothing.
