A client-side cms with a flat-file backend
This is the main code repository for the wiki-friendly blog-capable cms that I wrote.
Check out noddity.com for more details on the cms, the project in general, and easy installation instructions.
If you want your own copy of Noddity running on Github Pages (imagine it, a Github-backed wiki!) just fork the gh-pages branch of this repository.
If you're using Noddity as a wiki, bear in mind that the client caches all content, so while new visitors will see your changes as soon as you make them, it will take a while for them to show up in your browser.
