Installation

Copy the jar files into ~/.josm/plugins. On Windows XP, ~/.josm is usually C:\Documents and Settings\<login name>\.josm. Create a folder in there called 'plugins', and put the .jar files in there.

On Mac OS X you won't see these folders in the Finder, open Terminal to find the folders (UNIX folders with a dot as prefix are hidden).
