Documentation is a process of instruction or communication that provides information to users on how to interact with a computer system, product, procedure, or service. It is typically generated in advance of the anticipated use of a system, product, or service to anticipate user questions and provide answers to them. Documentation typically includes detailed descriptions of the system’s functionality, including operational instructions and examples of use. It may also include tutorials, code samples, and user manual for the system. It is an essential part of the software development process.
Documentation can be divided into three main categories – user documentation, system documentation, and reference documentation. User documentation describes how a software product is used. It usually includes a user manual which explains the layout of the system, explains how to perform functions, and provides examples of common tasks. System documentation, on the other hand, focuses on the technical aspects of the software. This type of documentation usually contains programming instructions, technical specifications, and maintenance instructions. Reference documentation, finally, is intended to provide additional information about a system, product, or service. It typically describes the architecture of the system, the libraries and components it uses, and the related software products.
Documentation is important from a technical and user experience standpoint. It helps ensure that software programs are used effectively and efficiently. Documentation also helps provide greater visibility and explainability of code, facilitating maintenance and support. Good documentation can improve user experience by making complex systems and processes easier to consume. Finally, comprehensive documentation enables users to help themselves, which frees up system support resources and saves time in the long run.
