-## a wiki mirror
-
-The simplest possibility is setting up a mirror. If a wiki exposes its git
-repository and has the [[plugins/pinger]] plugin enabled, then anyone can
-set up a mirror that will automatically be kept up-to-date with the origin
-wiki. Just clone the git repo, configure ikiwiki to use it, enable the
-[[plugins/pingee]] plugin in your configuration, and edit the origin wiki,
-adding a ping directive for your mirror:
-
- \[[!ping from="http://thewiki.com/"
- to="http://mymirror.com/ikiwiki.cgi?do=ping"]]
-
-The "from" parameter needs to be the url to the origin wiki. The "to" parameter
-is the url to ping on your mirror.
-
-Now whenever the main wiki is edited, it will ping your mirror, which will
-pull the changes from "origin" using git, and update itself. It could, in
-turn ping another mirror, etc.
-
-And if someone edits a page on your mirror, it will "git push origin",
-committing the changes back to the origin git repository, and updating the
-origin mirror. Assuming you can push to that git repository. If you can't,
-and you want a mirror, and not a branch, you should disable web edits on
-your mirror. (You could also point the cgiurl for your mirror at the origin
-wiki.)
