Documentation in software engineering

In software engineering, documentation refers to written records that describe how a software system works, how to use it, and how it was built. It includes user guides, technical specifications, code comments, and design decisions. Good documentation helps developers understand the software’s features, troubleshoot issues, and make future improvements efficiently. It serves as a reference that ensures everyone involved in the project, now and later, can access clear and consistent information about the system, facilitating maintenance, upgrades, and collaboration.
