Welcome to Warmane rns!
Hope this can help you get started!

First go to
https://www.warmane.com/download

Then you just follow the steps there, picking what Expansion you want, then the OS you are using i.e. Windows/Mac

From there should be like any other game, download it to where you want and that is where the WoW.exe will be
