+![ci](https://github.com/hey3/react-use-polling/actions/workflows/test.yml/badge.svg)
+
+`react-use-polling` is a react hooks library for polling asynchronous processes.
+
+## Instration
+
+```bash
+npm install react-use-polling
+```
+
+## Quikstart
+
+```tsx
+import { useState } from 'react'
+import { usePolling } from 'react-use-polling'
+
+function App() {
+  const [count, setCount] = useState<number>(0)
+
+  const updateCountAsync = async () => {
+    await new Promise(r => setTimeout(r, 100))
+    setCount(c => c + 1)
+  }
+
+  const { pause } = usePolling(updateCountAsync, 1000)
+
+  return (
+    <div>
+      <span>{count}</span>
+      <button onClick={() => pause()}>Pause Polling</button>
+    </div>
+  )
+}
+```
+
+## Hooks
+
+### `usePolling`
+
+This hook uses `requestAnimationFrame`.  
+It stops processing in the background to improving performance and reducing battery consumption.
+
+### `usePollingForce`
+
+This hook uses `setInterval`.  
+This will continue the polling process even in the background.
