+## 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.
+
+ % rm -rf foo
+ % git clone /srv/git/foo.git
+
+Finally, edit the setup file. Modify the settings for `srcdir`, `destdir`,
+`url`, `cgiurl`, `cgi_wrapper`, `git_wrapper`, etc to reflect where
+you moved things. Remember to run `ikiwiki --setup` after editing the
+setup file.
+
+## Enjoy your new wiki!
