Never done one, but seen as the inners unbolt, you should be able to simply unbolt the CV end (You'll need big bar and someone to stand on the brakes, do it with the wheel on, or if you cant, put the wheel bolts back in) then you should be able to unbolt the inner end and drop the shaft out.
take the old boot off, and there will probably be a circlip holding the shaft into the CV joint. Pop it out, slide new boot on, clean and regrease joint and reassemble.
