Can you add how to actually use the tools to the readme?

[dawnbomb]

Tools are only as useful as they are actually usable by others, and i don't know how to use this very well. I'd like to know about extracting, and repacking the files for the diffrent games.

For now xillia, but overall all of them. Can you add VERY CLEAR info to the readme?

Also i saw the other issue about reading decrypted files if keys are gone, please include instructions for that to!
