We have moved our documentation into the repository. Downloading the object will get you the documentation in a Documentation subdirectory. By doing it this way, it's easy to hand different documentation for different versions of the object.
At the moment we have a copy of the documentation at https://www.ats.amherst.edu/ACMapperObject/Documentation for those who don't want to download the package. Currently it's in need of a lot of work and the developer doc isn't complete. Changes made by developers to the documentation in the repository wouldn't be immediately reflected at this location.
