SEE ALSO

The documentation for Macaulay 2 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 Macaulay 2 variable prefixDirectory, but the best way to get to it is to viewHelp in Macaulay 2.

The home page for Macaulay 2 is http://www.math.uiuc.edu/Macaulay2/.
