The Beamer Class User Guide for version 3.67

beamer is a LATEX class for creating presentations that are held using a projector, but it can also be used to create transparency slides. Preparing presentations with beamer is different from preparing them with wysiwyg programs like OpenOffice.org Impress, Apple Keynote, KOffice KPresenter or Microsoft PowerPoint. A beamer presentation is created like any other LATEX document: It has a preamble and a body, the body contains \sections and \subsections, the different slides (called frames in beamer) are put in environments, they are structured using itemize and enumerate environments, and so on.
