The link on that kit is the exact same kit I used. Dead simple. The kit comes to be connected as follows:
Tyre valve (same as on a bike pump)
Which connects to the plastic bottle (you can make that out on the pic of the box)
Put brake/clutch fluid in the bottle (AFTER you've tested pressure!)
Fit cap (supplied in kit) onto resovoir
Crack the bleed nipple to make sure it's loose
Fit bleed pipe
Open tyre valve to pressure system, let it equalize, open bleed nipple until bubbles are gone.
It's all in the instructions anyway, so I've just wasted my time writing
