+Smart Citizen Kit firmware for SD
+=================================
+
+**Smart Citizen Kit SD firmware version for the Ambient Sensor Board.**
+
+This firmware is aimed to people wanting to log data in off-line mode, without internet connectivity, storing data on the built-in micro SD.
+
+
+##Steps
+
+1. **microSD**: We recomend formating **micro SD** cards using the official SD tool you can download [here](https://www.sdcard.org/downloads/formatter_4/).
+
+2. **RTC**: Place a **CR1220** cell battery on your kit. Before uploading the SD firmware use the on-line configuration tool to set your Wi-Fi credentials. Your kit will connect to the internet and sync its the internal clock with our remote servers.
+
+3. You can now install the **SD firmware** using the Arduino IDE. Ready!
+
+
+##Installation
+
+
+**The firmware is totally compatible with Arduino. You can upload the firmware using the [Arduino IDE](http://arduino.cc/en/main/software).**
+
+####Dependencies: 
+
+In order to compile and upload the firmware you will need to install the **SdFat** library for Arduino.
+
+Download the library [here](https://github.com/greiman/SdFat) and install the library following the [instructions](http://arduino.cc/en/Guide/Libraries).
+
+####Boards:
+
+* For SmartCitizen Kit version 1.0 select `Tools/Boards/Arduino Leonardo` on the Arduino IDE (ATmega 32U4 at 16Mhz) 
+
+* For SmartCitizen Kit version 1.1 select `Tools/Boards/Lylipad Arduino USB` on the Arduino IDE (ATmega 32U4 at 8Mhz) 
+
+##SD data format
+
 
 When using the **SD firmware** on the SCK, data is stored as **CSV** (comma separated) file on the SD card.
