 # Storage Backend: Web
 
-// todo  
+An AsyncStorage backend, targeting web platform. Uses either [`localStorage`](https://developer.mozilla.org/en-US/docs/Web/API/Window/localStorage) or [`sessionStorage`](https://developer.mozilla.org/en-US/docs/Web/API/Window/sessionStorage).  
 
 ## Installation
 
-// todo
+```bash
+$ yarn add @react-native-community/async-storage@next
+
+$ yarn add @react-native-community/async-storage-backend-web@next
+```
 
 ## Usage
 
-// todo
+```typescript
+
+import WebStorage from '@react-native-community/async-storage-backend-web';
+import AsyncStorageFactory from '@react-native-community/async-storage';
+
+type MyModel = {};
+
+
+const webStorage = new WebStorage(true);
+
+const storage = AsyncStorageFactory.create<MyModel>(webStorage);
+
+
+export default storage;
+```
+
+## Options
+
+`WebStorage` accepts a single `boolean` argument, deciding if `sessionStorage` should be used instead of `localStorage`. Default is `false`.
