Do you guys know a great beginner Arms Warri guide?

Hi all, as the title says, I need help to get into Arms Warri. I’ve been playing fury cause it’s pretty much chaos and you press glowing buttons. However, I’ve been trying myself to play Arms cause I want to learn it properly. I’ve checked the guides on wow Head etc. and I understand the opening rotation but I might just be too stupid for anything that follows after. In M+ I sometimes pop off and do crazy amounts of dmg but other packs I seem to completely mismanage my rage and rotation. Obviously, I need to practice and practice but I’ve not come to that lightbulb moment I am hoping for and wanted to see if you guys know a great guide to fully understand the spec?

Thank you in advance and any help is appreciated.
