+## internal pages and `aggregateinternal`
+
+This plugin creates a page for each aggregated item. 
+
+If the `aggregateinternal` option is enabled in the setup file (which is
+recommended), aggregated pages are stored in the source directory with a
+"._aggregated" extension. These pages cannot be edited by web users, and
+do not generate first-class wiki pages. They can still be inlined into a
+blog, but you have to use `internal` in [[PageSpecs|IkiWiki/PageSpec]],
+like `internal(blog/*)`.
+
+For backward compatibility, the default is that these pages have the
+".html" extension, and are first-class wiki pages -- each one generates
+a separate HTML page in the output, and they can even be edited.
+
+That turns out to not be ideal for aggregated content, because publishing
+files for each of those pages is a waste of disk space and CPU, and you
+probably don't want to allow them to be edited. So, there is an alternative
+method that can be used (and is recommended), turned on by the
+`aggregateinternal` option in the setup file.
+
+If you are already using aggregate and want to enable `aggregateinternal`,
+you should follow this process:
+
+1. Update all [[PageSpecs|ikiwiki/PageSpec]] that refer to the aggregated
+   pages -- such as those in inlines. Put "internal()" around globs 
+   in those PageSpecs. For example, if the PageSpec was `foo/*`, it should
+   be changed to `internal(foo/*)`. This has to be done because internal
+   pages are not matched by regular globs.
+2. Use [[ikiwiki-transition]] to move all existing aggregated `.html`
+   files. The command to run is `ikiwiki-transition aggregateinternal $srcdir`,
+   or if you have changed the `htmlext` option to something other than "html",
+   `ikiwiki-transition aggregateinternal $srcdir $htmlext`
+3. Turn on `aggregateinternal` in the setup file and rebuild the wiki.
