Dark Horse Witcher Comics

So, about a month ago I fell into the world of The Witcher, and have been stuck there ever since. I found out that there were a few different comic series, including this ongoing one from Dark Horse, but I can't seem to find fany real info on it.

So, are any of you familiar with these? Are they worth checking out? Do they follow along with the novels and games, or are they a separate continuity? etc, etc, etc.
