The following is from an old post when I did mine -
A ramp or pit would be perfect, if not, lift from passenger side (UK spec car) remove front wheel, only for extra space and stand placement. Get under car between wheel and jacking point, CDV is sort of directly under the front of the passenger seat, next to the gearbox.
It really is a very straight forward job, but do pinch the clutch hose otherwise it will pi55 fluid.
IIRC, 11mm and 17mm open ended to loosen and remove the CDV which actually sits in little bracket thingy, undo the smaller end first and it'll just spin off by hand. Same spanners to connect the ends you are left with.
Bleed the clutch for a few pumps and you're done.
