* Plug your server in wired Ethernet, or configure the wifi connection as explained [here](https://www.raspberrypi.org/documentation/configuration/wireless/wireless-cli.md). You can also mount the second partition of the SD card and edit the wpa-supplicant.conf file prior to boot the card for the first time - on Windows you can use [Paragon ExtFS](https://www.paragon-software.com/home/extfs-windows/), don't forget to unmount everytime for changes to take effect.
* Optional : You can **plug a screen** if you want to see how boot is going, and a keyboard if you want to have a **command-line access** to your server.
