MD-Pro is an Open Source Content Management System (CMS). Although originally the MD-Pro CMS was a spin-off of the PostNuke system, several changes over the years have set it apart. Despite those changes though, the two systems still share a common module system. That means that any module for PostNuke will most likely work in MD-Pro.
Most of the changes to MD-Pro have been in the area of theming and templates. MD-Pro makes it easy to have different templates for different modules in your site.
The download and installation instructions for MD-Pro are identical to the PostNuke instructions.
