Plenty of threads on the forum already...have a quick search at them. You have a few choices, some are more environmentally friendly than other, some involve more toil.
I think it depends how much you have. When I moved to this house 18 years ago it came up sporadically in the garden. I bruised the leaves and sprayed with Glyphosate and even though it reappeared from time to time and I can safely say I have had none now for around 10 years!
