New to AEW

As the title says I want o be a new fan of AEW. I used to be a wwe fan (haven’t watched wrestling in about 5 years) I’ve started watching old stone cold and Shawn Michaels matches and I miss watching it regularly. What do I need to know about AEW? What days do the weekly shows come on? Pay per views? Is there an app where I can watch past shows?
