is there like a tutorial that explains the game without having to play it again?

so long story short: 10 months ago i downloaded destiny 2 and did the free campaign and got to level 3 or 4 from what i remebers,and i also remebers being super stuck and confused

then i did the fianl shape free campaign up to where you meet an old friend or smth and then it blocks you with a pay wall

then the steam winter sales arrived and i got the witch queen dlc for like 4 euros (5 dollars or smth like that) and i was super hyped to play it since i also bought it on my birth day.But it was late and i decided to play it the next [day.Next](http://day.Next) day came and for some reason i lost ALL interest to the game and NEVER touched the dlc i bought and a week later or not touching the game (aside from pvp gamemodes) i deleted it since it was like 150gb

but now,almost a year later i got this urge to play the dlc BUT the probel is i dont remeber shit abt the mecanicks of the game and what to do,and i dont wanna replay it bc i dont wanna get re-stuck and re-confused

so is there like an in-game tutorial that explains everything?

any helps appreciated
