# Dedicated Server
The dedicated server is a version of Minecraft: Pi Edition modified to run in a headless environment. It loads settings from a ``server.properties`` file.
To use, install the ``minecraft-pi-reborn-server`` package and run ``minecraft-pi-reborn-server``. It will generate the world and ``server.properties`` in the current directory.
This server is also compatible with MCPE Alpha v0.6.1.
## Setup
### Debian Package
To use, install the ``minecraft-pi-reborn-server`` package and run ``minecraft-pi-reborn-server`` or use. It will generate the world and ``server.properties`` in the current directory.
### Docker Compose
Make sure you have ``qemu-user-static`` installed and ``binfmt`` setup.
```yml
version: "3.7"
services:
minecraft-pi:
image: thebrokenrail/minecraft-pi-reborn:server
volumes:
- ./minecraft-pi/data:/home/.minecraft-pi
- /usr/bin/qemu-arm-static:/usr/bin/qemu-arm-static
restart: always
stdin_open: true
tty: true
ports:
- "19132:19132/udp"
```
## Server Limitations
- Player data is not saved because of limitations with MCPE LAN worlds
- An easy workaround is to place your inventory in a chest before logging off
