Place the term "At RISE" flush left on the page, followed by a colon. For screenplays, use "Scene" or "Fade in" instead of "at RISE." Press return and set the cursor to type on the center of the page.
Write a description of the scene. For example, describe the room the characters appear in. Mention any significant details, such as an essential prop or placement of furniture. For instance: "A living room on a hot afternoon in the South. Old-fashioned furniture is strewn throughout the room."
Describe any characters who will be onscreen or on stage at this point and any of the actions they perform before the dialogue begins. For example: "Sally grabs a decanter sitting on a side table by the sofa and pours some brown liquid into a small tumbler. After a moment of reflection, she swigs back the drink and sits on the couch."
Add or delete details as necessary. Revise your introduction to suit the upcoming dialogue. Some writers prefer writing a lengthy description of the scene, while others may only need a few sentences to sufficiently set up the action.
