This is a simple tutorial to show how to set up Yun Buddy.
Step 1: Get the Arduino Yun on your network
If you are using a cable all you have to do is connect the Yun to your router.
If you are using wifi it gets a little more difficult.
By pressing and holding the wifi reset button on the board for 3 seconds the board will be set up as a device that your computer will be able to connect to.
Once connected point your browser to arduino.local.
Here you can configure your device to your network settings
