Cocos2d documentation presented in 2 forms: wiki pages and HTML pages autogenerated using doxygen. You can start to improve any direction, either wiki or generated docs, with usual account.
If you want improve generated docs, you’ll need to setup documentation build process
# Clone develop branch from git repo: https://github.com/cocos2d/cocos2d-x# install doxygen utility
# come to
./document in cloned sources and run
Doxygen will take all C*+ comments in source code and generate
./document/html subfolder with index.html page. Doxygen also can generate separate pages unbound from any source code: you just write header or source C*+ file that contains only one comment with some markup, see
./document/MainPage.h as example.
