This page explains the basic concepts for WoW development and UI Customization, by explaining basic parts of AddOns for those who are beginners.

What is the meaning of an AddOn:
Blizzard has made the decision that the user interface of World of Warcraft is fully customizable, modifiable and extendable. This is completely legal and is encouraged by Blizzard. A User Interface Modification (UI Mod for short) and AddOn is exactly the same thing, the difference is merely in their names. Usually "Mods" tend to refer to smaller things that only modify existing functionality of the user interface, whereas AddOns tend to add extra functionality. From here on, we will simply use "AddOn".

and like I said before and I will keep repeat it:

"AddOns is something a matter of taste, everyone like something else ... BBBBUUUTTTT there are some AddOns people must*** have (IMPORTANT, by must*** I mean, you must NOT have same addon as I use, BUT you need something that SUPPLIES almost the same things[Information]), cause this Info. you normally need.

for Example in PVP : Cooldown,Buffs,DeBuffs,Health,Mana,UI,Interupts... etc....
for Example in PVE: Aggro, Cooldown, Maps,Health,UI,Timers...etc...

Such a things are important for you and for the Team-Play.. and like that you can improve yourself even Better.

so let me show you the Steps, how to get AddOns:

1) First :

You must check the Version of the Game you play. The Version of the Game could be found at the Left-Bottom Side of the WoW-Game.

2) Second :

You need the right Websites to download the AddOns: For Example:

1) WoWInterface
2) CurseForge - I HIGHLY PREFER !!**
3) Curse

**CurseForge is like the Main-Data-Base of Curse - you will find more AddOns there and a lot more of Versions of an Specific AddOn.

3) Third :
Now after you got to the Website, we must search for the right version of an spec. AddOn. I will demonstrate that at the images that I am gonna upload.
a) Search for an specific addOn (Like Bagnon)
b) Search for the RIGHT Version. by Curse you click at "Other-Download" & by CurseForge you click "Files".
c) Search for Pages for the Right Version.
Demonstrating :
CurseForge:

Curse:

4) Fourth :

After you download everything, you must EXTRACT everything and put it in your WoW-Folders.
Example: "C:\...\World of Warcraft - Mist of Pandaria\Interface\AddOns\"
AddOns must be extract in the "...\Interface\AddOns\" .

What the mean of Extracting?

Extract means: To draw or pull out, often with great force or effort something to somewhere else.
and that is exactly what we gonna do. for extracting normally, you don't need any program cause the Windows have "7-zip"-program. But I prefer anyway a program called Winrar Download Winrar.
With such a programs, you can extract your downloaded File to somewhere else.

Where to Extract AddOns:
as I said before, AddOns must be extracted in the "...\Interface\AddOns\".

HOW to Move to the AddOn folder:
1) Open your World of Warcraft folder. (default is C: \Program Files\World of Warcraft\)
2) Go into the "Interface" folder.
3) Go into the "AddOns" folder.
-> and inside this folder you extract the Files from the Downloaded AddOns-File.
Looks Like that:

Installing is done !!

5) Fifth :
Start World of Warcraft & Make sure AddOns are installed:
After you start WoW and Log-in. You must check on things before you ENTER WORLD.
1) Make sure AddOns are installed
2) Make sure AddOns are CHECKED

How TO DO that:
before you Enter-World (At the Character Select screen), at the LEFT-Bottom side of the Screen, there is the "AddOn" Button.
Looks like that:
[img overlay=true]http://i.imgur.com/ZSHMd0T.jpg[/img]

after you click that Button you will see this: -> and like this you can CHECK if everything got installed and checked.

!! If the button is NOT there: means you did not install the addOns properly. Look at the above screenshots. Try repeating the steps or getting someone who knows more about computers than you do to help.


6) Sixth :
Ingame :

Sometimes you will see different instantly (Example if you download Bartender), and sometimes you must configure everything yourself. I can't explain every AddOn in curse or in Curse-Forge because there is a lot of addOns. normally there is a description for every addOn you download. But I can show you where to find their Options. there is Two-Ways for that.
1) in Interface
2) Small-Icon at the Mini-map. (if you installed more than 1 AddOn at once, the Icons would be one over the other, in a situation like this, you can move them as you wish.

Interface:

Configuration:

With the Configuration, you can play a lot and almost change everything.
