+# Curie
+
+The Intel Curie is a microcontroller for the Internet of Things. It is the platform used by the Intel Arduino/Genuino 101 and the Intel TinyTILE.
+
+For more info about the Curie platform go to: [http://www.intel.com/content/www/us/en/do-it-yourself/edison.html](http://www.intel.com/content/www/us/en/do-it-yourself/edison.html).
+
+## How to Install
+
+You would normally install Go and Gobot on your workstation. When you execute the program code, it will communicate with the connected microcontroller using the Firmata protocol.
+
+```
+go get -d -u gobot.io/x/gobot/...
+```
+
+## How To Use
+
+```go
+// code here...
+```
