What are stage directions in a script used for?

Stage directions in a script are used to provide guidance and instructions for the actors, directors, and production team on how to perform and stage the play. They describe the physical actions, movements, and gestures of the characters, as well as the settings, props, and other elements of the play. Stage directions help to create a visual and spatial understanding of the play, allowing for consistency and clarity in the production. They also provide important cues for lighting, sound effects, and other technical aspects of the performance. Overall, stage directions help to bring the script to life on stage and enhance the audience's experience.
