 ## How it works?
 
 ### Android
+The `Android` app can open either `Recent` folder or `Download` folder.
 The plugin will show the available file manager apps in the bottom popup and you can select one app to open.
-That app will open with the `Download` folder which is a public folder.
+That app will open with the given folder in selected app.
 
 ### iOS
-Plugin will open the `Files` app in iOS. You need to add the following code snippet in `Info.plist` to view your app folder inside `On My iPhone`.
-Also, you need to save at least one file to view your app's folder
+The `iOS` app can open app's document folder and it's sub directory if provided.
