Just got Hearts of Iron IV, I know we have more than a few players here, any good tips/tricks/guides to make it less daunting for a beginner?

I just grabbed HoI IV just recently, but am kind of daunted by the game so far, I tried the in game tutorial briefly, but it didn't give me a good idea on what the hell I was doing, I felt like I was reading gibberish. I did download the Hearts of Iron IV 2025-2026 beginner guide video on youtube, but haven't had the time to watch it just yet, and am aware of the wiki too. I'm wondering what current players feel like the best resources for a beginner to get into the game are? I appreciate any help and look forward to tackling the game and it making sense because it looks and sounds awesome ;)
