It is very straightforward, as fordie says.
Whilst you're at it, examine the friction plates to make sure there's still some friction material on them (there's not a great deal of thickness when new, mind, so don't expect millimetres of the stuff), and make sure the basket grooves aren't excessively notched.
What's "excessive"?
Well. it's all a matter of judgement...
And don't overtighten the clutch spring allen screws when you refit the pressure plate.
