Daniel Frisk has provided the following instructions on how to get started.
- Minecraft – Pi Edition runs on Raspbian “wheezy” with XWindows. If you need to set that up, visit http://www.raspberrypi.org/downloads and follow the detailed instructions within.
- Boot up your Raspberry Pi with Raspbian. If you haven’t set XWindows to start automatically upon boot, type in “startx”.
- Next click the icon for LXTerminal to open a new terminal window. Use the following commands (in bold) to download and launch:
To decompress it: tar -zxvf minecraft-pi-0.1.1.tar.gz
To run it: cd mcpi
Followed by minecraft-pi
