To enable Juice on your web site, you need to load a small number of JavaScript and CSS files on to that site.
The relevant files are contained in in zip files downloadable from here:
http://code.google.com/p/juice-project/downloads/list
To reflect developments in the project the zip file names include the software version number. Always load the latest version.
There are two zip files for each version juice-{version}.zip and juice-basic-{version}.zip.
The juice-basic file contains a minimum install of Juice, ideal for starting and then adding the occasional, individually downloaded, extension. The juice file contains all extensions and examples in that version of Juice.
