To install the software, you will need to use the command line. Because Minecraft will only work if you have keyboard, mouse and monitor connected to your Raspberry Pi, there is little point installing it using SSH.

It's easy to install if your Pi doesn't already have it, in the command terminal, run this command at the shell prompt:

sudo apt-get install minecraft-pi 

sudo apt-get install minecraft-pi 

Old instructions

Originally you'd have to run the following but its no longer required now that you can run the single command above!

wget https://s3.amazonaws.com/assets.minecraft.net/pi/minecraft-pi-0.1.1.tar.gz
tar -zxvf minecraft-pi-0.1.1.tar.gz

wget https://s3.amazonaws.com/assets.minecraft.net/pi/minecraft-pi-0.1.1.tar.gz
tar -zxvf minecraft-pi-0.1.1.tar.gz

The end result of all this will be a folder called mcpi in your home directory.
