Software documentation

Software documentation or source code documentation is written text that accompanies computer software. It either explains how it 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 documentation is the description of what a particular software does or shall fulfill. It is used throughout development to communicate what the software does or shall do. It is also used as an agreement or as the foundation for agreement on what the software shall do. Requirements are produced and consumed by everyone involved in the production of software: end users, customers, product managers, project managers, sales, marketing, software architects, usability experts, interaction designers, developers, and testers, to name a few. Thus, requirements documentation has many different purposes. Requirements come in a variety of styles, notations and formality.  more
