Welcome to the official ElvUI wiki
Make sure to check out the wiki-sidebar at the right side -->
Installing or updating ElvUI works like every other AddOn.
1) Download the AddOn (Retail / Classic)
2) Right-click and extract it.
3) Then move the folder(s) to:
World of Warcraft / _retail_ / Interface / AddOns
World of Warcraft / _classic_ / Interface / AddOns
We recommend that you delete the old AddOn folders first, to prevent lingering files causing issues.
Updating AddOns will not cause settings to be lost, as all settings are stored in the
 ElvUI is only
ElvUI_OptionsUI(loadable on demand) in your ingame AddOn list.
Every other AddOn starting with
ElvUI_XXXX is made by the community and could be outdated if the author is inactive.
 ElvUI is not a "collection" of multiple AddOns, like some people believe.
If you want to use external AddOns for specific features like Chat, ActionBars, NamePlates - you have to disable the ElvUI module for this feature first.
