 ### Connect Pi to the network
 
-Turn on Pi by using the micro USB cable and the power supply. Use the Ethernet cable to connect Pi to your wired network or follow the [instructions from the Raspberry Pi Foundation](https://www.raspberrypi.org/documentation/configuration/wireless/) to connect Pi to your wireless network. After your Pi has been successfully connected to the network, you need to take a note of the [IP address of your Pi](https://www.raspberrypi.org/documentation/remote-access/ip-address.md).

 > [!NOTE]
 > Make sure that Pi is connected to the same network as your computer. For example, if your computer is connected to a wireless network while Pi is connected to a wired network, you might not see the IP address in the devdisco output.
