-# Multiplayer
-MCPI-Reborn supports two ways to play multiplayer.
-
-## Local Network (LAN)
-This is also supported by vanilla MCPI. Just load a world in MCPI and other devices on the network can join.
-
-## External Servers
-Unlike vanilla MCPI, MCPI-Reborn allows you to natively join a server outside of the local network. Just modify `~/.minecraft-pi/servers.txt` and it should show up in MCPI's server list.
