This is the documentation for the Yada Wiki WordPress plugin. You can download Yada Wiki from the WordPress.org plugin repository. I try to keep the plugin up to date and test it with each new WordPress version.
I made a screencast tutorial on how to use the plugin to create a wiki for your WordPress site. It provides a good overview. If you want more information then I suggest checking out the Yada Wiki documentation wiki link below.
By default, Yada Wiki uses the built-in roles and permissions of the Posts content type. Occasionally people want to setup roles specifically for the wiki. I found that the free version of the Advanced Access Manager plugin that is in the WordPress repository is pretty straightforward. I wrote an article that shows how to use it with Yada Wiki.
