Instructions for using a computer device or program. Documentation can appear in a variety of forms, the most common being manuals. When you buy a computer product (hardware or software), it almost always comes with one or more manuals that describe how to install and operate the product.

These forms of documentation make it much easier to deliver the specific information a user needs when he or she needs it.
