The normal install instructions for Box Of Stops recommend starting with Noobs installed on your Raspberry Pi. Noobs is the New Out Of Box Software, and comes with everything you'll need to run Box Of Stops.
The other option is a minimal Raspbian install. This is actually quicker to download and install, but more difficult to get correctly configured.
Installation
To install Box Of Stops on a raw Raspbian installation, please ensure Raspbian has been installed first, and an internet connection has been set up.
From then the missing dependencies will be Pygame and Java.
The following command will install Pygame:
sudo apt-get install python-pygame
File:Install-pygame
And this will install Java:
sudo apt-get install oracle-java8-jdk
File:Install-java
Once these two installations are complete, Box Of Stops may be installed in the normal way.
