+# Getting Started with Vue Redux
+
+[Vue Redux](https://github.com/reduxjs/vue-redux) is the official [Vue](https://vuejs.org/) UI bindings layer for [Redux](https://redux.js.org/). It lets your Vue components read data from a Redux store, and dispatch actions to the store to update state.
+
+## Installation
+
+Vue Redux requires **Vue 3 or later**, in order to make use of the Vue Composition API.
+
+### Installing with `npm` or `yarn`
+
+To use Vue Redux with your Vue app, install it as a dependency:
+
+```bash
+# If you use npm:
+npm install @reduxjs/vue-redux
+
+# Or if you use Yarn:
+yarn add @reduxjs/vue-redux
+```
+
+You'll also need to [install Redux](https://redux.js.org/introduction/installation) and [set up a Redux store](https://redux.js.org/recipes/configuring-your-store/) in your app.
+
+Vue-Redux is written in TypeScript, so all types are automatically included.
+
+## API Overview
+
+### `provideStoreToApp`
+
+Vue Redux includes a `provideStoreToApp` function, which makes the Redux store available to the rest of your app:
+
+```typescript
+import { createApp } from 'vue'
+import { provideStoreToApp } from '@reduxjs/vue-redux'
+import { store } from './store'
+
+import App from './App.vue'
+
+const app = createApp(App)
+provideStoreToApp(app, { store })
+app.mount('#app')
+```
+
+### Compositions
+
+Vue Redux provides a pair of custom Vue compositions that allow your Vue components to interact with the Redux store.
+
+`useSelector` reads a value from the store state and subscribes to updates, while `useDispatch` returns the store's `dispatch` method to let you dispatch actions.
+
+```vue
+<script setup lang="ts">
+import { useSelector, useDispatch } from '@reduxjs/vue-redux'
+import { decrement, increment } from './store/counter-slice'
+import { RootState } from './store'
+
+const count = useSelector((state: RootState) => state.counter.value)
+const dispatch = useDispatch()
+</script>
+
+<template>
+  <div>
+    <div>
+      <button aria-label="Increment value" @click="dispatch(increment())">
+        Increment
+      </button>
+      <span>{{ count }}</span>
+      <button aria-label="Decrement value" @click="dispatch(decrement())">
+        Decrement
+      </button>
+    </div>
+  </div>
+</template>
+```
