These are good beginner guides.
A tldr for this game is that, like every moba, the game revolves around objective taking. What that means becomes more nuanced as you learn more about the game. I might write something up later, but the guides i linked are pretty good. Ofc the best way to learn when new is to just play, and remember, when ppl give you advice or tips, to try to understand the reasoning behind it
Oh two things i kinda want to add
The game is constantly updated in kind of unsubtle ways, so make sure any hero guide you read is updated
And also a general piece of advice i would give is to try to think at least two steps ahead (ex. conditions are good for me to take a camp -> i think about ways i can take advantage of the pressure gained from the camp)/make sure the decisions you are making are towards some end
