+INTRODUCTION
+============
+This is a POC (Proof of Concept) for implementing
+ANCS (Apple Notification Center Service)with 
+NRF51822-mKit (mbed) platform.
+
+The code is not meant to be use for implementation,
+whatsoever.
+
+I'm not intent to further enhancing this code.
+The sole purpose is to show that we can use
+SoftDevice client api for doing ANCS with NRF51822-mkit.
+(At this time, BLE API doesn't expose Gatt Client API)
+
+This program code are bypassing mbed BLE API and use
+Soft Device (S110) Gatt Client API directly.
+
+If you want to explore the code, S110 API Reference will
+be handy.
+
+I know, there are many bugs, and things not implemented
+correctly. But again, the purpose of this code is just
+to show thant Gatt Client API is indeed doable. 
+
+
+WHAT NEXT?
+==========
+Since with this code, ANCS with mbed (NRF51822-mkit) is
+doable, the next step is to implement GATT CLIENT API on 
+mbed BLE API. 
+That should make programming more understandable (and
+perhaps portable to other platform) than using SD API
+directly.
+
+
+HOW TO TEST THIS OUT?
+=====================
+You gonna need:
+1. iOS7 (iPhone/iPad)
+   *recomended: iPush Test, free app to generate test notification.
+    but if you can generate notification by yourself
+    anything will be sufficient.
+2. NRF51822-mKIT, connected to PC
+   (debug log and the notification itself will
+     be print out via usb com port).
+   *teraterm etc is needed to access com port.
+    (depend on your platform) 
+     
+Ready for the action!
+1. Compile the code, transfer the binary file to mkit.
+2. Use teraterm etc, to connect to mkit com port. 
+3. Press reset. LED1(advertise) should turn on.
+   You should see Appendix 1 Log.
+4. On iOS7, select "Settings", "Bluetooth".
+   You should see "ANCC" on the devices list.
+   Click it to connect. LED2(connected) should turn on.
+5. A Dialog will appear: "Bluetooth Pairing Request"
+   Press "Pair"
+   You should see Appendix 2 Log.
+
+   That's it you ready to receive notification.
+   There's a free app on app store for generating
+   push notification. Search "push test" on app store.
+ 
+6. Run iPush Test app
+7. Click "Local Push Test"
+8. You will receive notification in about 1 minute.
