-# AzureIoT - Azure IoT library for Arduino
+# AzureIoT - Azure IoT Hub library for Arduino
 
-This library is a port of the [Microsoft Azure IoT device SDK for C](https://github.com/Azure/azure-iot-sdks/blob/master/c/readme.md) to Arduino. It allows you to use your Arduino/Genuino with the [Azure IoT Hub](https://azure.microsoft.com/en-us/services/iot-hub/).
+This library is a port of the [Microsoft Azure IoT device SDK for C](https://github.com/Azure/azure-iot-sdks/blob/master/c/readme.md) to Arduino. It allows you to use several Arduino compatible boards with Azure IoT Hub.
 
-For the Arduino/Genuino [MKR1000](https://www.arduino.cc/en/Main/ArduinoMKR1000) or [Zero](https://www.arduino.cc/en/Main/ArduinoBoardZero) and [WiFi Shield 101](https://www.arduino.cc/en/Main/ArduinoWiFiShield101) only.
+Currently supported hardware:
+- Atmel SAMD Based boards
+  - Arduino/Genuino [MKR1000](https://www.arduino.cc/en/Main/ArduinoMKR1000)
+  - Adafruit [Feather M0](https://www.adafruit.com/products/3010)
+  - Arduino/Genuino [Zero](https://www.arduino.cc/en/Main/ArduinoBoardZero) and [WiFi Shield 101](https://www.arduino.cc/en/Main/ArduinoWiFiShield101) 
+- ESP8266 based boards with [esp8266/arduino](https://github.com/esp8266/arduino)
+  - SparkFun [Thing](https://www.sparkfun.com/products/13711)
+  - Adafruit [Feather Huzzah](https://www.adafruit.com/products/2821)

-## Getting started
-
-See the [Microsoft Azure IoT device SDK for C - Arduino WiFi Shield 101 and MKR1000 Setup Guide](https://github.com/Azure/azure-iot-sdks/blob/master/c/doc/run_sample_on_arduino_wifi101.md).
+## Prerequisites
+
+You should have the following ready before beginning with any board:
+-   [Setup your IoT hub](https://github.com/Azure/azure-iot-sdks/blob/master/doc/setup_iothub.md)
+-   [Provision your device and get its credentials](https://github.com/Azure/azure-iot-sdks/blob/master/doc/manage_iot_hub.md)
+-   [Arduino IDE 1.6.8](https://www.arduino.cc/en/Main/Software)
+-   Install the `AzureIoTHub` library via the Arduino IDE Library Manager
+
+## ESP8266
+##### Sparkfun Thing, Adafruit Feather Huzzah, or generic ESP8266 board
+
+1. Install esp8266 board support into your Arduino IDE.
+    * Start Arduino and open Preferences window.
+    * Enter `http://arduino.esp8266.com/stable/package_esp8266com_index.json` into Additional Board Manager URLs field. You can add multiple URLs, separating them with commas.
+    * Open Boards Manager from Tools > Board menu and install esp8266 platform 2.1.0 or later 
+    * Select your ESP8266 board from Tools > Board menu after installation
+    
+2. Open the AzureIoTHub ESP8266 sample from the Arduino IDE File->Examples menu.
+3. Update Wifi SSID/Password in simplesample_http.ino 
+    * Ensure you are using a wifi network that does not require additional manual steps after connection, such as opening a web browser.
+4. Update IoT Hub Connection string in simplesample_http.c
+
+
+## Adafruit Feather M0
+1. Install Feather M0 board support into your Arduino IDE.
+    * Start Arduino and open Preferences window.
+    * Enter `https://adafruit.github.io/arduino-board-index/package_adafruit_index.json` into Additional Board Manager URLs field. You can add multiple URLs, separating them with commas.
+    * Open Boards Manager from Tools > Board menu and install Adafruit SAMD Boards 1.0.7 or later.
+    * Select your Adafruit Feather M0 from Tools > Board menu after installation
+2. Install the [Adafruit WINC1500 wifi library](https://learn.adafruit.com/adafruit-feather-m0-wifi-atwinc1500/using-the-wifi-module)
+3. Install the `RTCZero` library from the Arduino IDE Library Manager.
+2. Open the AzureIoTHub SAMD sample from the Arduino IDE File->Examples menu.
+3. Update Wifi SSID/Password in simplesample_http.ino 
+    * Ensure you are using a wifi network that does not require additional manual steps after connection, such as opening a web browser.
+4. Update IoT Hub Connection string in simplesample_http.c
+
+## MKR1000 or Zero + Wifi101
+1. Open the AzureIoTHub SAMD sample from the Arduino IDE File->Examples menu.
+2. Update Wifi SSID/Password in simplesample_http.ino 
+    * Ensure you are using a wifi network that does not require additional manual steps after connection, such as opening a web browser.
+3. Update IoT Hub Connection string in simplesample_http.c
