 ## Requirements
 
 - Turtle WoW / any 1.12 client.
 - Optional but recommended: **[SuperWoW](https://github.com/balakethelock/SuperWoW)** – lets all accounts in the same
   game folder share data through `imports\AdeAlts.txt`. Without it, nothing is shared between accounts unless you enable chat sync with `/ade chat` (cooldowns only).
-- Optional: pfUI (minimap button docking and skin).
+- Optional: pfUI (pfUI window look and minimap button docking). Not required: without pfUI the addon uses classic Blizzard-style windows.
