I've been listening to some Roll 20 campaign via Youtube,and I'd like to give one a shot,but I feel that before I do this, I should read up a bit on the basic rules being used for D&d campaigns,as the last time I played a d&d game,of any description was many years ago when I played NeverWinter Nights,and I'm sure that everything has changed since then. Would you be able to link me on where I could find the relevant information,regarding this?
