World of WarCraft

How to Install Addon:

1. Download your chosen interface.
2. Extract the files to a folder on your desktop.
3. Open your WoW folder.

If using a PC, the typical default install path is:
C:\Program Files\World of Warcraft

If using a Macintosh, the typical default install path is:
Macintosh Main HD (or whatever you renamed it to, if you did)/Applications/World of Warcraft

If using a Linux Ubuntu, the typical default install path is:
/home/user/.wine/drive_c/World of Warcraft

4. In the WoW folder, create a new folder called Interface (if it doesn’t already exist).
5. Open that folder, create another one inside it, called AddOns (again, if it doesn’t already exist).
6. Open the AddOns folder.
7. Copy the files from the folder on your desktop into the AddOns folder.
8. Your final path should look like:

PC:
C:\Program Files\World of Warcraft\Interface\AddOns\Someaddon\files
C:\Program Files\World of Warcraft\Interface\AddOns\QuestHelper\files

Mac:
Macintosh HD/Applications/World of Warcraft/Interface/Addons/Someaddon/files
Macintosh HD/Applications/World of Warcraft/Interface/Addons/QuestHelper/files

Ubuntu [Screen]:
/home/użytkownik/.wine/drive_c/World of Warcraft\Interface\AddOns\Someaddon\files
/home/użytkownik/.wine/drive_c/World of Warcraft\Interface\AddOns\QuestHelper\files

9. Log into game. At the character select screen, there should be an "AddOns" button in the lower left corner. Click on that. If any of the mods in the list that pops up say "out of date" or some such, choose the "Load Outdated AddOns" option.

10. Log the rest of the way into game, you should be up and running now. :)
