Technical writing is a style of formal writing used in technical fields such as computer hardware and software, chemistry, robotics, biotechnology and consumer electronics. Its purpose is to explain technology and related issues to technical and non-technical readers. For example, technical writing can be for programmers who need to use a new software library, or for consumers who want to operate a new laser printer.

Technical writing consists of general information derived from existing documentation on the research and development of a technology, as well as specific knowledge provided by experts in that technical field. In order to successfully communicate to the readers, strong presentation and teaching skills are required. The writing needs to be accurate, precise and to the point, using languages and formats that the readers can easily comprehend.

Good technical writing relies on a thorough understanding of a technology and its applications, as well as an accurate analysis of the readers and their needs. It translates complex technical concepts and instructions into a piece of simple writing that enables the readers to use this technology sufficiently. To achieve this, the writing needs to be reviewed by both technical experts and English editors before it reaches the readers.
