+## Multiplayer
+
+Basic LAN multiplayer is available on the Windows build.
+
+- Hosting a multiplayer world automatically advertises it on the local network
+- Other players on the same LAN can discover the session from the in-game Join Game menu
+- Game connections use TCP port `25565` by default
+- LAN discovery uses UDP port `25566`
+- You can override your in-game username at launch with `-name`
+
+Example:
+
+```powershell
+Minecraft.Client.exe -name Steve
+```
+
+This feature was introduced from the work in [PR #96](https://github.com/smartcmd/MinecraftConsoles/pull/96) and is based on [LCEMP](https://github.com/LCEMP/LCEMP/).
