I did mine recently mate, couldn't find a DIY, but it's all quite self explanatory once you get going.
Things to note would include, nearside wiring can be unplugged by removing the interior trim around the rear airbag unit, there's 3 plugs there, it's quite a tight fit but doable... lifting the new boot into position on your own is achievable but nicer if there's two of you.
Allocate some time to do this, as it's quite a lengthy process with the tailgate trim refitting etc. Take your time and you'll be Golden, good luck mate!
