If this plugin is enabled, then a sidebar is added to pages in the wiki.
The content of the sidebar is simply the content of a page named
-"sidebar".
+"sidebar" (ie, create a "sidebar.mdwn").
Typically this will be a page in the root of the wiki, but it can also be a
[[SubPage]]. In fact, this page, [[plugins/sidebar|plugins/sidebar]], will
be treated as a sidebar for the [[plugins]] page, and of all of its
SubPages, if the plugin is enabled.
-This plugin is included in ikiwiki, but is not enabled by default.
+Note that to disable a sidebar for a [[SubPage]] of a page that has a sidebar,
+you can create a sidebar page that is completely empty. This will turn off
+the sidebar altogether.
-[[tag type/chrome]]
+Warning: Any change to the sidebar will cause a rebuild of the whole wiki,
+since every page includes a copy that has to be updates. This can
+especially be a problem if the sidebar includes [[inline]] or [[map]]
+directives, since any changes to pages inlined or mapped onto the sidebar
+will change the sidebar and cause a full wiki rebuild.
