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

+Warning: Any change to the sidebar will cause a rebuild of the whole wiki,
+since every page includes a copy that has to be updated. 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.
