https://en.wikipedia.org/wiki/Technical_documentation
In engineering, technical documentation refers to any type of documentation that describes handling, functionality and architecture of a technical product or a product under development or use.[1][2][3] The intended recipient for product technical documentation is both the (proficient) end user as well as the administrator / service or maintenance technician. In contrast to a mere "cookbook" manual, technical documentation aims at providing enough information for a user to understand inner and outer dependencies of the product at hand.
Traditionally, most forms of technical documentation have lacked recognized standards, though this is changing.[4] So far, ISO has published a series of standards related to technical product documentations and these are covered by ICS 01.110.[5] The ones that are not covered by ICS 01.110 are listed in the subsection below.
