+# Multiplayer Lan Example
+
+This is a sample multiplayer example showing off how to set up a lobby + dedicated server with godot-rust.
+
+
+
+Largely adapted from FinePointCGI's Godot multiplayer tutorial:
+
+[Basics Of Multiplayer In Godot 4! - YouTube](https://youtu.be/e0JLO_5UgQo?si=mHYry88uC8j4r2DM)
+
+
+
+To run as dedicated server, run the exported version of this game from the command line with the arguments ``--headless --server``
