On the Internet, a tutorial is a document, software, or other media created for the purpose of instruction for any of a wide variety of tasks.
For media to be properly identified as a tutorial -- the following attributes should be present:
    * A presentation of content, usually with an example or examples, often broken up into discrete modules or sections.
    * Some method of review that reinforces or tests understanding of the content in the related module or section.
    * A transition to additional modules or sections that builds on the instructions already provided. Tutorials can be linear or branching.
While many writers refer to a mere list of instructions or tips as a tutorial, this usage can be misleading.

n computing, a tutorial is a computer program whose purpose it is to assist users in learning how to use (parts of) a software product such as an office suite or any other application, operating system interface, programming tool, or game. There are two kinds of software tutorials: movie tutorials that you watch, and interactive tutorials where you follow on-screen instructions (and in some cases watch short instruction movies), whereupon you do the tutorial exercises and get feedback depending on your actions.
