-## Edge Usage
-
-::alert{type=danger}
-❗️ If you really need to call `useModal()`{lang=ts} outside of `<script setup>`, there is a way to approach it but you must use it carefully.
-::
-
-There is a optional property that is `options.context`{lang=ts}, it accept a vfm instance. If given a vfm instance to `options.context`{lang=ts}, `useModal()`{lang=ts} will use the vfm instance internally instead of the injected vfm instance. This will allow you to use `useModal()`{lang=ts} outside out `<script setup>`.
-
-You have to manually calling `modalInstance.destroy()`{lang=ts} whenever you no longer need the dynamic modal instance anymore. Here are some key points that you need to know about `modalInstance.destroy()`{lang=ts} and `modalInstance.close()`{lang=ts}:
-
-- Calling `modalInstance.destroy()`{lang=ts} will delete the modal instance inside of `vfm.dynamicModals`. So if you have an opened modal, the modal will be closed if you calling `modalInstance.destroy()` without calling `modalInstance.close()`{lang=ts}.
-- Calling `modalInstance.close()`{lang=ts} will not delete the modal instance inside of `vfm.dynamicModals`. So if you keep calling the `useModal()`{lang=ts}, the length of `vfm.dynamicModals` will keep growing until you have memory leak (see [#277](https://github.com/vue-final/vue-final-modal/issues/277)). This is the reason why you have to manually call `modalInstance.destroy()`{lang=ts} whenever you no longer need the dynamic modal instance anymore (usually in `onClosed` hook).
-- Without calling `modalInstance.destroy()`{lang=ts} correctly, the memory leak might occur both on server side (Nuxt 3) and on client side (Vue 3 SPA).
-
-### Vue 3
-
-- You have to create a plugin that export the `vfm` instance:
-  ```ts [@/plugins/vue-final-modal.ts]
-  import { createVfm } from 'vue-final-modal'
-
-  export const vfm = createVfm()
-  ```
-- Then you have to import the `vfm` instance in your `main.ts` file and register it as a Vue plugin:
-  ```ts [main.ts]
-  import { createApp } from 'vue'
-  import App from './App.vue'
-  import { vfm } from '@/plugins/vue-final-modal'
-
-  const app = createApp(App)
-
-  app.use(vfm).mount('#app')
-  ```
-- Then you can using `useModal()`{lang=ts} everywhere by given the same `vfm` instance to `options.context`{lang=ts}:
-  ```ts
-  // Anywhere outside out script setup
-  import { VueFinalModal, useModal } from 'vue-final-modal'
-  import { vfm } from '@/plugins/vue-final-modal'
-
-  export function openModalConfirm() {
-    const modalInstance = useModal({
-      context: vfm,
-      component: ModalConfirm,
-      attrs: {
-        onClosed() {
-          modalInstance.destroy()
-        },
-      },
-      slots: { default: '<p>The content of the modal</p>' }
-    })
-
-    modalInstance.open()
-  }
-  ```
-
-### Nuxt 3
-
-- You have to create a plugin that export the `vfm` instance and register it as a Vue plugin:
-  ```ts [@/plugins/vue-final-modal.ts]
-  import { createVfm } from 'vue-final-modal'
-  import { defineNuxtPlugin } from '#app'
-
-  export const vfm = createVfm() as any
-
-  export default defineNuxtPlugin((nuxtApp) => {
-    nuxtApp.vueApp.use(vfm)
-  })
-  ```
-- Then you can using `useModal()`{lang=ts} everywhere by given the same `vfm` instance to `options.context`{lang=ts}:
-  ```ts
-  // Anywhere outside out script setup
-  import { VueFinalModal, useModal } from 'vue-final-modal'
-  import { vfm } from '@/plugins/vue-final-modal'
-
-  export function openModalConfirm() {
-    const modalInstance = useModal({
-      context: vfm,
-      component: ModalConfirm,
-      attrs: {
-        onClosed() {
-          modalInstance.destroy()
-        },
-      },
-      slots: { default: '<p>The content of the modal</p>' }
-    })
-
-    modalInstance.open()
-  }
-  ```
