First of all, a big thank you to the developers of these addons. They are a great deal of help.
There is quiet alot of addons in this pack, not all are used at the same time.
I have different characters and different addons are used for each. My main is the shadowpriest kriswag you can get a good idea of how it functions in a raid setup.
There are some videos of me using this ui on my stream link:
1The usual, go open your wow folder,
2)Move your current interface + WTF folder somewhere safe e.g Desktop.
3)Unzip the downloaded file into your WoW folder.
4)Go into the downloaded WTF folder and change the Account name, Server name, and character name to your own.
5)Open WoW & enjoy
