Getting up and running with Raspberry PI ( Wifi )

Download the Raspbian from the following link:

https://www.raspberrypi.org/downloads/raspbian/

Follow the following link to get the image burned onto an SD Card:

https://www.raspberrypi.org/documentation/installation/installing-images/README.md

To get the wireless up and running, you need to purchase a USB-Wifi.

I used the following:

 http://www.amazon.com/Wifi-Antenna-Raspberry-Pi-Instructions/dp/B00H95C0A2/

Note: No monitor or Keyboard are required to get the Raspberry Pi up and running.

You can easily SSH to Raspberry Pi by connecting it over the ethernet. It will be assigned an IP provided by the DHCP of the Router. You can figure out the IP from the Router’s Connected Devices page. Use that IP to login into the Raspberry PI.
