Documentation needs to conform to the standards.
For each module, they need:
-list of C++ classes (using the \module command)
-list of QML types (using the \qmlmodule command) if applicable
-page which lists examples (applicable for modules with many examples)
The work and status are kept here: http://qt-project.org/wiki/Qt5DocumentationProject
For Qt Script, the landing page (qtscript-index.html) needs to exist and link to the C++ classes. See wiki for specifications.
