User guide

A user guide, user manual, '''owner's manual or instruction manual''' is intended to assist users in using a particular product, service or application. It is usually written by a technician, product developer, or a company's customer service staff.

Most user guides contain both a written guide and associated images. In the case of computer applications, it is usual to include screenshots of the human-machine interface(s), and hardware manuals often include clear, simplified diagrams. The language used is matched to the intended audience, with jargon kept to a minimum or explained thoroughly.

Until the last decade or two of the twentieth century it was common for an owner's manual to include detailed repair information, such as a circuit diagram; however as products became more complex this information was gradually relegated to specialized service manuals, or dispensed with entirely, as devices became too inexpensive to be economically repaired.

Owner's manuals for simpler devices are often multilingual so that the same boxed product can be sold in many different markets. Sometimes the same manual is shipped with a range of related products so the manual will contain a number of sections that apply only to some particular model in the product range.

With the increasing complexity of modern devices, many owner's manuals have become so large that a separate quickstart guide is provided. Some owner's manuals for computer equipment are supplied on CD-ROM to cut down on manufacturing costs, since the owner is assumed to have a computer able to read the CD-ROM. Another trend is to supply instructional video material with the product, such as a videotape or DVD, along with the owner's manual.

Many businesses offer PDF copies of manuals that can be accessed or downloaded free of charge from their websites. Provided by Wikipedia
