An introduction for John Steinbeck's novel Of Mice and Men would need to include a description of the main characters, the setting (time and place) and the plot of the story. Therefore, an introduction would need to include the following information.
Characters needing to be named are Lennie Small, George Milton, Curley, Slim, Crooks, Candy, Carlson, and Curley's wife.
The setting includes both time the story takes place and where the story takes place. The story is set in the Salinas Valley (California) during the Great Depression (the 1930s).
The plot, simplistically, is about two men who are following their dreams to purchase land of their own and be their own bosses. The conflicts which arise are those which coincide with Lennie given his diminished mental capacity.
