+Some settings cannot be configured on the web, for security reasons or
+because misconfiguring them could break the wiki. To change these settings,
+you can manually edit the setup file, which is named something like
+"foo.setup". The file lists all available configuration settings
+and gives a brief description of each.
+
+After making changes to this file, you need to tell ikiwiki to use it:
+
+ % ikiwiki -setup foo.setup
+
+## Customizing file locations
+
+As a wiki compiler, ikiwiki builds a wiki from files in a source directory,
+and outputs the files to a destination directory. The source directory is
+a working copy checked out from the version control system repository.
+
+When you used `auto.setup`, ikiwiki put the source directory, destination
+directory, and repository in your home directory, and told you the location
+of each. Those locations were chosen to work without customization, but you
+might want to move them to different directories.
+
+First, move the destination directory and repository around.
+
+ % mv public_html/foo /srv/web/foo.com
+ % mv foo.git /srv/git/foo.git
+
+If you moved the repository to a new location, checkouts pointing at the
+old location won't work, and the easiest way to deal with this is to delete
+them and re-checkout from the new repository location.
