Currently FreeFOAM comes with man-pages for all the applications and utilities. However, most of them are little more than stubs and need expanding. Further, the User Guide and the Programmer’s Guide from OpenFOAM are also included in the package.

The Doxygen API-Documentation can be automatically generated when compiling FreeFOAM, or it can also be accessed directly from here.
