built-in <a href="/wiki/Special:MyLanguage/Manual:Namespace" title="Special:MyLanguage/Manual:Namespace">namespaces</a>, it is possible to add custom namespaces to a MediaWiki installation, to further separate content and allow more logical organization. </p><p>Custom namespaces are simple to manage using the <code><a href="/wiki/Special:MyLanguage/Manual:$wgExtraNamespaces" title="Special:MyLanguage/Manual:$wgExtraNamespaces">$wgExtraNamespaces</a><span style="display:none"><a href="/wiki/Manual:$wgExtraNamespaces" title="Manual:$wgExtraNamespaces"> </a></span></code> configuration directive. It is also possible to define alias names for custom (and also predefined) namespaces, using the <code><a href="/wiki/Special:MyLanguage/Manual:$wgNamespaceAliases" title="Special:MyLanguage/Manual:$wgNamespaceAliases">$wgNamespaceAliases</a><span style="display:none"><a href="/wiki/Manual:$wgNamespaceAliases" title="Manual:$wgNamespaceAliases"> </a></span></code> configuration directive. Some extensions make it easy for you to create custom namespaces.
