 ## Using with Vue 2
 
-When using Vue 2 install [@vue/composition-api](https://github.com/vuejs/composition-api#npm) via npm/yarn first:
-
-``` bash
-npm i @vue/composition-api --save-dev
-```
-
-Then install the plugin for Vue:
-
-``` js
-import Vue from 'vue'
-import VueCompositionAPI from '@vue/composition-api'
-
-Vue.use(VueCompositionAPI)
-```
-
-After that make sure to change the imported Multiselect module to:
-
-``` js
-import Multiselect from '@vueform/multiselect/dist/multiselect.vue2.js'
-```
-
-## Using with Nuxt.js
-
-First you need install [@nuxtjs/composition-api](https://composition-api.nuxtjs.org/getting-started/setup):
+``` vue
+<template>
+  <div>
+    <Multiselect
+      v-model="value"
+      :options="options"
+    />
+  </div>
+</template>
 
-``` bash
-npm i @nuxtjs/composition-api --save
-```
+<script>
+  import Multiselect from '@vueform/multiselect/multiselect.vue2.js'
 
-Then you need to enable it as a module in `nuxt.config.js`:
+  export default {
+    components: {
+      Multiselect,
+    },
+    data() {
+      return {
+        value: null,
+        options: [
+          'Batman',
+          'Robin',
+          'Joker',
+        ]
+      }
+    }
+  }
+</script>
 
-``` js
-{
-  buildModules: [
-    '@nuxtjs/composition-api/module'
-  ]
-}
+<style src="@vueform/multiselect/themes/default.css"></style>
 ```
 
-After that make sure to change the imported module to Vue 2 version of Multiselect:
-
-``` js
-import Multiselect from '@vueform/multiselect/dist/multiselect.vue2'
-```
+#### Using with < Vue 2.7
 
-For more information on using `@nuxtjs/composition-api` read [their documentation](https://composition-api.nuxtjs.org/).
+Switch to [`<= 2.4.2`](https://github.com/vueform/multiselect/tree/2.4.2) to use the Multiselect with Vue.js `< 2.7`.
