+Warning: Any change to the sidebar page 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 an
+[[ikiwiki/directive/inline]] directive, since any changes to pages inlined
+into the sidebar will change the sidebar and cause a full wiki rebuild.
+
+Instead, if you include a [[ikiwiki/directive/map]] directive on the sidebar,
+and it does not use the `show` parameter, only adding or removing pages
+included in the map will cause a full rebuild. Modifying pages will not.
