+## Window Size and Position
+
+- This allows the last set window size and position to be remembered and applied if application is closed. 
+
+```sh
+nativefier 'https://open.google.com/'
+  --inject window.js
+```
+Notes:
+- [Inject](https://github.com/nativefier/nativefier/blob/master/API.md#inject) the following javascript as `windows.js` to prevent the window size and position to reset.
+```javascript
+function storeWindowPos() {
+window.localStorage.setItem('windowX', window.screenX);
+window.localStorage.setItem('windowY', window.screenY);
+}
+
+window.moveTo(window.localStorage.getItem('windowX'), window.localStorage.getItem('windowY'));
+setInterval(storeWindowPos, 250);
+```
