  ==== Installing Modules
  
  Modules do not require any installation and are not specific to any operating system. Simply download the module file (which will usually have a .VMOD extension, and open it from the Module Manager). Once you've opened a module successfully it will be displayed in the Module Manager's "Module Library", making it easier to find for subsequent games.
  
  Modules made for older versions of Vassal are usually compatible with Vassal {project-version}, although they may be missing some graphics or functionality available in Vassal {project-version}.
