Documentation refers to the process of creating and maintaining written records that provide information about a specific subject. This can include manuals, reports, guides, and other materials that explain how to use a product, follow a procedure, or understand a concept. Good documentation helps users find the information they need quickly and ensures consistency in understanding. In various fields, such as software development, medicine, and education, documentation plays a crucial role in communication and knowledge sharing. It serves as a reference for users and professionals, helping them to perform tasks accurately and efficiently while preserving important information for future use.
