 # Version 1 of the Experimental AWS SDK for Arduino
 
-An experimental SDK for contacting AWS Services on Arduino-compatible devices. Currently with DynamoDB support and potential Kinesis support.
+An experimental SDK for contacting AWS Services on Arduino-compatible devices. Currently it supports Amazon DynamoDB, Amazon Kinesis and Amazon SNS. More services coming soon.
 
-All DynamoDB operations are supported. The code for creating, serializing, and deserializing Kinesis input and output objects is included, but the devices that the experimental SDK has been tested on do not have readily available HTTPS support. This code has been included so it can be used by those who want to do further experimenting with Kinesis and HTTPS.

 The SDK is extensible to non-Arduino-compatible devices by implementing the interfaces in `DeviceIndependentInterfaces.cpp`/`.h`. See `SparkAWSImplementations.cpp`/`.h` and `GalileoAWSImplementations.cpp`/`.h` for examples of this.
 
+## Folder
+
+/common contains all the common source code
+/sparkcore contains Spark IO Core device-specific implementations
+/edison contains Intel Edison device-specfic implementations
+/galileo contains Intel Galileo device-specific implementations
+
+Simply copy the device-specific implementations based on the device that you are working on in the Common directory so you can test out your samples using Arduino IDE.

 Happy experimenting!
