Good news - it's not too hard if you are thinking about it.
Install clutch pedal assembly - you need the entire pedal assembly because the "gas" pedal is drive by wire. Install clutch switch for cruise control.
Use VCDS to tell the car's computer that a manual is installed and not an automatic - it's a simple change of 1 code.
Install clutch master hydraulic cylinder and line.
Install transmission.
IMHO, an interior seat swap is a lot easier though.
