I am trying to make it a collection of info about Configuring Fvwm, along with example configurations. I even made it colorful with syntax highlighting of the Fvwm config format.
Feel free to let me know of anything you notice about the FvwmWiki. If you would like to contribute you can find the code on github.
Is this GitHub fvwmwiki still active? I created a fork having a look at the Jekyll markup language. Looks good and is easy to use. Would be nice to add practical and helpful samples to Fvwm Wiki if this GitHub is the one.
The wiki is now part of the fvwm.org website, similar structure, it is just no longer a separate project. (note the main page of the wiki even states this, FvwmWiki)
There are even some instructions for how the wiki is setup.
