Writing of introduction to the play,characters involved in the play and their roles,chapters or scenes and where they are taking place and who is being involved. The time when events are taking place also (day,afternoon,evening,night).Appropriate naming of the play (if not yet named by client or client isn't satisfied the current title). I also proof read and edit.So I can do it before forming the appropriate script for a play.Observing spelling,punctuation and grammatical flow.
