-## About Permission:
-
-
-Since version 1.2.0, two functions and a property were added:
-
-```javascript
-// --- function
-async checkRecordPermission() // return promise
-async requestRecordPermission() // return promise
-
-// --- property
-recordPermission = 'unknow' or 'granted' or 'denied', default is 'unknow'
-```
-
-After incall-manager initialized, it will check current state of record permission and set to `recordPermission` property.
-so you can just write below code in your `ComponentDidMount` like:
-
-```javascript
-if (InCallManager.recordPermission !== 'granted') {
-    InCallManager.requestRecordPermission()
-    .then((requestedRecordPermissionResult) => {
-        console.log("InCallManager.requestRecordPermission() requestedRecordPermissionResult: ", requestedRecordPermissionResult);
-    })
-    .catch((err) => {
-        console.log("InCallManager.requestRecordPermission() catch: ", err);
-    });
-}
-```
-
-We use android support library v4 to check/request permissions.  
-You should add `compile "com.android.support:support-v4:23.0.1"` in `$your_project/android/app/build.gradle` dependencies on android.
-
-
-**NOTE for android:**
-
-React Native does not officially support api 23 currently ( it is on api 22 now. see: [RN known issues](https://facebook.github.io/react-native/docs/known-issues.html#android-m-permissions)) and android supports request permission at runtime since api 23, so it will always return 'granted' immediately after calling `checkRecordPermission()` or `requestRecordPermission()`.
-
-If you really need the functionality, you can do the following to make them work but at your own risk:  
-( I've tested it though, but who knows :) )
-
-Step 1: change your `targetSdkVersion` to 23 in `$your_project/android/app/build.gradle`  
-Step 2: override `onRequestPermissionsResult` in your `MainActivity.java` like:  
-
-```
-    @Override
-    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
-        InCallManagerPackage.onRequestPermissionsResult(requestCode, permissions, grantResults);
-        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
-    }
-```
-
-Then you can test it on android 6 now.
-
-**Another thing you should know is:**
-
-If you change targetSdkVersion to 23, the `red box` which React Native used to display errors in development mode requires permission `Draw Over Other Apps`.  
-So in **development mode**, you should manually grant permission in `app settings` on your device or declare `android.permission.SYSTEM_ALERT_WINDOW` in your manifest.  
-You don't have to do this in **release mode** since there is no red box.
