I like to use "wikis" for documentation for many of the projects I work on. Most of you are probably familiar with the term wiki, coming from the Hawaiian word for quick (wikiwiki). There are quite a few PHP-based wiki tools out there, including mediawiki (which Wikipedia uses), PmWiki and DokuWiki. In this article we will look at PhpWiki, and we'll show you how to configure and use it with your own projects!
They briefly cover the history behind wikis before moving straight into the installation/configuration of the package. Thankfully, wikis have been made to be pretty straightforward - simple special formatting characters are used to style the content in all of the typical HTML elements. They don't provide a complete guide to this formatting, but there are plenty of resources around that talk about that.
They move on to the next logic step every site owner wants - how to customize the look to what you want (or to fit into the rest of your site). There are a few other configuration notes that they make and links to other resources including the software's homepage and documentation.
