Let's see how to set up Raspberry Pi:

1. Place your SD card into the SD card slot on the Raspberry Pi. It will only fit one way
2. Plug your keyboard and mouse in to the USB ports on the Raspberry Pi
3. Connect your HDMI cable from your Raspberry Pi to your monitor or TV
4. Connect a Wi-Fi dongle to one of the USB ports (unless you have a Raspberry Pi 3)
5. The Raspberry Pi is powered by the micro USB power supply
