+
+Automatically refetch queries when they become stale in Pinia Colada.
+
+## Installation
+
+```sh
+npm install @pinia/colada-plugin-auto-refetch
+```
+
+## Usage
+
+```js
+import { PiniaColadaAutoRefetch } from '@pinia/colada-plugin-auto-refetch'
+
+// Pass the plugin to Pinia Colada options
+app.use(PiniaColada, {
+  // ...
+  plugins: [
+    PiniaColadaAutoRefetch(),
+  ],
+})
+```
+
+You can customize the refetch behavior individually for each query with the `autoRefetch` option:
+
+```ts
+useQuery({
+  key: ['todos'],
+  query: getTodos,
+  autoRefetch: false, // disable auto refetch
+})
+```
