Want to try it out? First of all, you need a Debian based Linux distribution and KDE. Second, add the following to you /etc/apt/sources.list:
sudo apt-get update
and install it:
sudo apt-get install isimoin
Now you may use your new ruby:
isimoin create-instance my_wiki
To run the wiki:
isimoin run-instance my_wiki
This should bring up a Konqueror showing the freshly created wiki.
The wiki should be awailable in the start menu, too. Have a look into the Internet section. Depending on your KDE/Gnome version, it may take a while, or even a restart of the desktop environment, to show up…
You may always contact me at email@example.com or leave a comment.
Good luck, and see you at irc:freenode.org/#isimoin.
