+## Usage Example
 
-// ...
+```tsx
+import { View, Text, TouchableOpacity, StyleSheet } from 'react-native';
+import { saveImageToGallery } from 'react-native-img-buffer-save';
 
-const result = multiply(3, 7);
+export default function App() {
+  const saveImg = () => {
+    const imgBytes = Uint8Array.from([0, 1, 2, 3, 4, 5, 6, 7, 8, 9]); // some image;
+
+    saveImageToGallery(img); // Accepts Uint8Array
+    // or
+    saveImageToGallery(img.buffer); // Accepts ArrayBuffer
+  };
+
+  return (
+    <View style={styles.container}>
+      <TouchableOpacity onPress={saveImg}>
+        <Text>Save IMG to gallery</Text>

+    alignItems: 'center',
+  },
+});
 ```
