A technical manual is a document that provides detailed instructions and information about a specific product, system, or process. It is designed to help users understand how to operate, maintain, or troubleshoot the item in question. Technical manuals often include diagrams, specifications, and step-by-step procedures to ensure clarity and ease of use. These manuals are commonly used in various fields, including engineering, software development, and manufacturing. For example, a technical manual for a computer program might explain how to install the software, while a manual for a machine could detail its operational procedures and safety guidelines.
