Where are the Greenfoot and GeoGebra chapters?
The Greenfoot and GeoGebra chapters have been left out of this edition of the manual. These programs rely on software called a Java virtual machine, which is currently being optimised for the Raspberry Pi to improve performance. You can look forward to enjoying these chapters once we are happy that your user experience will be of the same high quality as the chapters themselves!
