My Beginner's Guide to HSR

I was helping someone out in the comments a few days ago and figured I should go the extra mile to make a 'crash course' for all things HSR now that 2.0 is on the way. I hope a lot of new players can see this! As I said in the disclaimer, some of this info MAY BE incorrect or incomplete - I did this mostly from memory, experience, and a bit of research. Please correct me if you see any mistakes. Hope this helps! Send this to someone you know if they're just starting out/want to get into HSR! Also, the stickers/images are from Google, property of MiHoYo. EDITED TO ADD: More info about the importance of speed!
