All readers expect documents to include some sort of introduction. Whether they are reading a home page on a Web site or an opening paragraph in a research report, readers want to learn quickly what a document is about. As you begin to draft, consider strategies you might use to frame and introduce your main point. Keep track of those strategies so that you can revise your introduction later on. Many writers find that crafting an effective introduction is the most challenging part of drafting. If you run into difficulties, put your introduction aside and come back to it after you’ve made more progress on the rest of the document. There’s no law that says you have to write the introduction first.
