 Once connected to a device, the BluetoothDevice object can discover services ([BluetoothService](lib/src/bluetooth_service.dart)), characteristics ([BluetoothCharacteristic](lib/src/bluetooth_characteristic.dart)), and descriptors ([BluetoothDescriptor](lib/src/bluetooth_descriptor.dart)).
 The BluetoothDevice object is then used to directly interact with characteristics and descriptors.
 
-## Setup
-### Change the minSdkVersion for Android
-
-Flutter_blue is compatible only from version 19 of Android SDK so you should change this in **android/app/build.gradle**:
-```dart
-Android {
-  defaultConfig {
-     minSdkVersion: 19
-```
-### Add permissions for Bluetooth
-We need to add the permission to use Bluetooth and access location:
-
-#### **Android**
-In the **android/app/src/main/AndroidManifest.xml** let’s add:
-
-```dart 
-	 <uses-permission android:name="android.permission.BLUETOOTH" />  
-	 <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />  
-	 <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>  
- <application
-```
-#### **IOS**
-In the **ios/Runner/Info.plist** let’s add:
-
-```dart 
-	<dict>  
-	    <key>NSBluetoothAlwaysUsageDescription</key>  
-	    <string>Need BLE permission</string>  
-	    <key>NSBluetoothPeripheralUsageDescription</key>

 ## Troubleshooting
-### Scanning for service UUID's doesn't return any results
+### When I scan using a service UUID filter, it doesn't find any devices.
 Make sure the device is advertising which service UUID's it supports.  This is found in the advertisement
 packet as **UUID 16 bit complete list** or **UUID 128 bit complete list**.
