Explanation:
Dialogue
stage directions (as you should know where things are probably going to be)
technical instructions( because you wouldn't want your actor or actress to get injured at the last minute and check if things are secure properly them you're good to go)
and also setting to see if nobody falls and if you don't want a setting let the actors and actresses know so they can imagine if things are there by themselves.
BTW I do drama so I kinda know and you wouldn't want any of your cast to be injured unlike mine before the play.
