Instiki is a Ruby-based Wiki clone written by David Heinemeier Hansson. Until Version 0.11 it was maintained by Alexey Verkhovsky - currently it is maintained by Matthias Tarasiewicz. It is very easy to install and set up, and can be used under Linux, Mac OS X or Windows. It accomplishes its two-step install (install Ruby, run instiki.rb) by using WEBrick, a web server, and Active Record, a major component in the Ruby on Rails framework. Until Instiki 0.11.0, released March 19, 2006, Madeleine, a persistence layer that ships with the standard distribution of Ruby, was used.
