|Customize Your Callisto Experience|
The Callisto Experience starts with a small download in the form of the Eclipse Platform Runtime Binaries. From this starting point, using the Callisto Discovery Site, you can add as few or as many of the features produced by the ten projects involved in the Callisto release train as you need.
What do you need?
Eclipse 3.2 is required for Callisto. There is no upgrade path from previous versions of Eclipse.
