How do you persuade software engineers to write technical documentation? By letting them stay in their (development) environment.
The integrated development environment Eclipse offers several tools, which not oly help software engineers create software documentation. They also make the work of technical writers easier. At the tekom conference 2014, Frank Ralf presented some of these tools: Javadoc, Mylyn WikiText, IBM Information Architecture Workbench, and oXygen.
