Help me?

I wanted to install AddOns for ESO but i couldn't find any AddOn folder. When i open up my The Elder Scrolls Online folder it only has 3 folders inside: depot, game and vo_en. I cant find anything related to addons there. Inside depot there are folders called _databuild and video. Inside the game folder there is a folder called client. Inside the folder named client there is a folder called _databuild. Inside vo_en there is a folder called _databuild. Do i need to creat one myself? And where?
