The documentation for Macaulay2 is available locally starting in ${prefix}/share/doc/Macaulay2/Macaulay2Doc/html/index.html, where ${prefix} is replaced by the directory prefix used when the package was installed. The directory is available as the value of the Macaulay2 variable prefixDirectory, but the best way to get to it is to run the command viewHelp in Macaulay2.

The home page for Macaulay2 is http://www.math.uiuc.edu/Macaulay2/.
