Jade is commercial software from Materials Data, Inc. Version 5 is pretty dated (version 9.5 is current). You can find tutorials and user guides online, but perhaps you should contact the vendor directly: .
A quick search revealed "free downloads" of older Jade 5 from various websites, but to my knowledge the program, even the older releases, are not free software. I would strongly discourage you from using pirated versions of this software, if that is what they are.
