Getting Into Warhammer 40K - My First Steps 

Nice video! I tried to get into the Warhammer table top game years ago I bought a couple of space marine kits, and found it fun to paint them. But I gave up on it for a few reasons. I gave up on it because I found it to be too expensive, I didn't have any friends that wanted to play with me, and I went to the Games Workshop store a couple times and I found that half of the people that play the game don't shower on a regular basis. But the books might be fun to read.

Where to begin....can't go wrong with Abnett. There is a lot of lore to get into so some of the books get a little repetitive. A lot of the adeptus astartes books are non stop action. The Heresy books are good but not for a starting point until you get a grasp of the history, what the Heresy is, the chaos gods (Slaneesh is who you were thinking of), the Primarchs, and the various chapters. I liked the Souldrinkers series as they go against the grain of the other astartes. There are some decent blood angel series and also can't go wrong with the Wolves. There are a few from the Chaos perspective. But they all run together. Caiphas Cain is about as comedic as they get. Reminded me of Bill the Galactic Space Hero. Never played the tabletop. Have played the Fantasy Flight ttrpg a few times. Have painted miniatures but they are freightfully overpriced but will buy their paint, although Vallejo is my second choice. If you look up some Golden Demon winners, white amazing, they probably kit bashed several hundred dollars in mimis. But at least you can now talk about grimdark.
