Editing PmWiki (section)

===Wiki structure===
Wiki pages are contained within namespaces, called "wiki groups".<ref name=wikigroups>{{cite web|url=https://www.pmwiki.org/wiki/PmWiki/WikiGroup|title=PmWiki / WikiGroup}}</ref> Multiple namespaces can be used, and each namespace can have its own configuration options, add-ons, access control, skin, styles, sidebar (menu), the language of the content, and interface.<ref name=localcust>{{cite web|url=https://www.pmwiki.org/wiki/PmWiki/LocalCustomizations|title=PmWiki / Local customizations}}</ref>

Hierarchically, every page is contained in a namespace. It is possible to display and navigate through pages in a tree-like structure with a "wiki trail".<ref name=wikitrails>{{cite web|url=https://www.pmwiki.org/wiki/PmWiki/WikiTrails|title=PmWiki / WikiTrails}}</ref> Through recipes, it is possible to have a flat structure (no wiki groups), multiple nested groups, or sub-pages.

Special namespaces are "PmWiki", Site, SiteAdmin, and Category which contain the documentation and some configuration templates.
