Don't recall any instructions, the first time I did it-just follow common sense, always make sure your lights/ignition is off.
From memory though:
Remove the back cover housing
You will see a Red/Black igniter, twist that gently and pull down, carefully pull out the wires connected to it at the side
Unscrew the bulb housing and gently pull down, do not touch the glass part of the bulb
The Bulb type is D2S, Facelifted MINI's 05 onwards.
It's pretty straightforward when you see start dis-assembling, just don't go in heavy handed
