Warhammer 40k 10th Edition Battle Report - Chaos Knights vs Space Wolves (2000 points)

Well, I played my 2000 points of Space Wolves against 2000 points of Chaos Knights in a game of Warhammer 40,000 10th Ed. It went terribly, my troops got slaughtered and I conceded at the start of my 3rd turn. Was the army selection terrible? If so what would have been good to swap out and drop in? Or could I have won this with this army? If so, how could I have deployed and played better? Apologies for the low-rent video production, if you can suggest a way I COULD have won this seemingly unwinnable battle - I'd appreciate it.
Thanks!
