I'm not sure if everyone knows this, but Universe has a huge article library on frequently asked questions!
There are hundreds of articles listed. About Commerce, Blocks- you name it, we probably have an article about it!
If you're an introvert (like me 
), but you've got a few questions about navigating Universe, my best suggestion is to check there first! Sometimes, you'll find answers you weren't even looking for.
