PmWiki is a wiki-based system for collaborative creation and maintenance of websites. PmWiki pages are like normal web pages, except they have an "Edit" link that makes it easy to modify existing pages and add new pages into the website, using basic editing rules. You do not need to know or use any HTML or CSS. Page editing can be left open to the public or restricted to small groups of authors.
PmWiki is extendable by "Cookbook Recipes" which are code fragments that can be added to the local configuration file. If a feature is available through such a recipe it is marked as "Plugin" in the feature table.
