I just got the starter set and will be DMing my first ever game of DnD with some friends in a few days.
How far should I read through the Mine of Phandelver campaign to be ready for the first session?
Edit, more details: I've watched 10+ hours of DnD on youtube, so I'm somewhat familiar with the concepts. The people I'm playing with have barely ever heard of DnD, so with my limited time I want to make sure I'm prepared enough to give them a favorable experience that they'll want to pursue.
I've managed to nail down ~3 hours or so with them, but since it's a starter book I'm not sure if 3 hours will only get us through the first chapter, half of it, to chapter 3, etc. I've got limited time and a tough crowd to impress so I want to pre-read only what I need to, and practice that, thanks!
TlDr: How far can a brand new DnD crowd get in 3~ hours through the Lost Mine of Phandelver campaign?
