Download EllesmereUI.
Free, and three ways to get it.

Pick whichever suits you. The addon is identical either way

Then what?
Three steps and you are playing.

  1. Install it. An addon manager handles this for you. Installing by hand means dropping the folders into World of Warcraft/_retail_/Interface/AddOns.
  2. Pick your modules. When EllesmereUI first runs, you will be asked which modules you want to use (you can enable or disable any at a later time).
  3. Pick a preset or start customizing. When you first login, EUI will set its default layout to be similar to your Blizzard Edit Mode. Start from that and begin customizing, or browse through our collection of community made presets!
