'''Software documentation''' is written text or illustration that accompanies computer software or is embedded in the source code. The documentation either explains how the software operates or how to use it, and may mean different things to people in different roles.

[[Documentation]] is an important part of software engineering. Types of documentation include:

* Requirements[[Requirement]]s – Statements that identify attributes, capabilities, characteristics, or qualities of a system. This is the foundation for what will be or has been implemented.

* Architecture/Design – Overview of software. Includes relations to an environment and construction principles to be used in design of software components.

* Technical – Documentation of code, algorithms, interfaces, and APIs.

Line 83:

Typically, the user documentation describes each feature of the program, and assists the user in realizing these features. It is very important for user documents to not be confusing, and for them to be up to date. User documents do not need to be organized in any particular way, but it is very important for them to have a thorough [[Index (publishing)|index]]. Consistency and simplicity are also very valuable. User documentation is considered to constitute a contract specifying what the software will do. [[API Writer]]s are very well accomplished towards writing good user documents as they would be well aware of the software architecture and programming techniques used. See also [[technical writing]].

User documentation can be produced in a variety of online and print formats.<ref>{{cite webbook| url = http://dl.acm.org/citation.cfm?id=2775457| title = RH Earle, MA Rosso, KE Alexander (2015) User preferences of software documentation genres.

# '''Tutorial:''' A [[tutorial]] approach is considered the most useful for a new user, in which they are guided through each step of accomplishing particular tasks.<ref name=kdp>{{cite web

# '''Thematic:''' A [[Theme (literature)|thematic]] approach, where chapters or sections concentrate on one particular area of interest, is of more general use to an intermediate user. Some authors prefer to convey their ideas through a knowledge based article to facilitate the user needs. This approach is usually practiced by a dynamic industry, such as [[Information technology]].<ref name=kbad>{{cite web
