-At this point, your wiki should already be visible in `/var/www/mirror.example.com`, the `destdir`. You can edit it and changes should show up automatically in the `destdir`.

-However, you need yet another clone for this, the `srcdir` being used internally by the web interface of Ikiwiki. So clone the `repository` elsewhere:

-    edit index.mdwn
-    git commit index.mdwn
-    git push

-This will refresh the main page of the wiki, for example.

 You will also need a webserver to serve the content in the `destdir`
 defined above. We assume you will configure a virtual host named `mirror.example.com`. Here are some examples on how to do those, see [[!iki setup]] and [[!iki tips/dot_cgi]] for complete documentation.

+In the above configuration, the master git repository is still on the main site. If that site goes down, there will be delays when editing the wiki mirror.
