Interface AddOn Kit

Overview
The AddOn Kit is an executable created by Blizzard to enable AddOn authors to extract the art, XML and Lua files from the current installation of WoW so they can use them in AddOns and learn from them.

It was designed and used before V4.0.1 of WoW came out and it switched to the Blizzard Launcher download system. Although the AddOn Kit does still work Blizzard stopped suggesting it was used which is likely because as mentioned earlier it extracts what you have installed but as the Blizzard Launcher can now let you play before all downloads are complete you may well not have all the relevant files to extract.

To use the new "built-in" extractor, see Viewing Blizzard's interface code.

Blizzard Disclaimer

Important disclaimer: Customizing the interface is a very technical endeavor, and you should not attempt it unless you have a good working knowledge of XML and Lua. There is no official support for modifying the WoW interface. If you experience any issues with the interface after modifying it, you can disable any unofficial add-ons and changes in the AddOns menu at the character selection screen. Blizzard Technical Support cannot assist with setting up any kind of interface modification. However, you can find information for developing or installing add-ons in the}} UI & Macros Forum on the World of Warcraft website.
