New dude, help

Hey everyone, i delved into this TTRPG way to sudenly. Some of my friends invited me to play DnD for the 1st time and I went reluctantly. Now Im dreading the weeks or months of wait until I play again. I never thought that my child like imagination was still this intact, and in need of expression, but that session really did it for me.

Now, Ive found the concept of solo rpg and IronSworn, I think I have most thins ready, but have no idea how to start and conduct my campaign, how much should I relly on the oracle, and all that stuff.

Sorry if its a very common question here, but ive been doing this literally for a week and a half xD
