+
+## :book: Rule Details
+
+This rule reports the `watch()` after `await` expression.  
+In `setup()` function, `watch()` should be registered synchronously.
+
+<eslint-code-block :rules="{'vue/no-watch-after-await': ['error']}">
+
+```vue
+<script>
+import { watch } from 'vue'
+export default {
+  async setup() {
+    /* ✓ GOOD */
+    watch(() => { /* ... */ })
+
+    await doSomething()
+
+    /* ✗ BAD */
+    watch(() => { /* ... */ })
+  }
+}
+</script>
+```
+
+</eslint-code-block>
+
+## :wrench: Options
+
+Nothing.
