 This means you don't need a separate 'Unity' Input box and you can use all native text functions such as `Select`, `Copy` and `Paste`
 
 ## Usage
-1. Simply copy the files in `release/NativeEditPlugin` into your existing unity project asset folder.
-2. If using Unity >= 5.6 make sure that your Plugins/Android/AndroidManifest.xml defines 
-    ```
-    <activity android:name="com.bkmin.android.UnityPlayerNotOnTopActivity"
-       android:label="@string/app_name">
-    ```
-    instead of
-    ```
-    <activity android:name="com.unity3d.player.UnityPlayerNativeActivity"
-        android:label="@string/app_name">
-    ```
-    Note that there can be multiple Android manifests in a Unity project (if you have multiple Android plugins) and Unity merges them to a single manifest when building. The `activity` on the manifest closest to the root level of `Plugins/Android` directory seems to override definitions in other manifests so make sure to modify that manifest
-
-    If another plugin you're using is overriding the `UnityPlayerActivity` and the input field appears invisible you need to modify the overriding `UnityPlayerActivity` so that it doesn't appear on top of native views, see https://github.com/YousicianGit/UnityNativeEdit/issues/34.
-    
-    You can refer to sample `AndroidManifest.xml` in `/Plugings/Android` folder.
