+       For Git, you need two repositories, of which one should be bare
+       (meaning that it does not have a working tree checked out). We call
+       the bare repository the "repo" and the other the "srcdir" ($srcdir).
+       There are [other
+       ways](http://blog.madduck.net/vcs/2007.07.11_publishing-git-repositories)
+       to do the following, but this might be easiest:
+
+                       REPOSITORY=./wiki.git
+                       # SRCDIR is where ikiwiki compiles from. You thus need
+                       # to set $srcdir in ikiwiki.setup appropriately. The
+                       # -wc in the name suggests "working clone" because
+                       # $SRCDIR holds a Git repository with a working tree.
+                       SRCDIR=./wiki-wc
+                       cd $SRCDIR
+                       git init
+                       echo "Initial index page" > index.mdwn
+                       echo .ikiwiki > .gitignore
+                       git add index.mdwn .gitignore
+                       git commit -m'Initial commit'
+                       git config receive.denyNonFastForwards true
+                       git config core.bare true
+                       mv .git $REPOSITORY
+                       test -d .ikiwiki && mv .ikiwiki ..
+                       cd ..
+                       rm -r $SRCDIR
+                       git clone -l -s $REPOSITORY $SRCDIR
+                       test -d .ikiwiki && mv .ikiwiki $SRCDIR
+
+       It is **paramount** that you **never** push to the Git repository in
+       `$SRCDIR` ([this FAQ entry explains
+       why](http://git.or.cz/gitwiki/GitFaq#head-b6a3d85f677763313159eb39f7dbf4579d4ee28b)).
+       Instead, if you want to work on the wiki from a remote machine, clone
+       `$REPOSITORY`, using either the `git` transport (if available), or
+       `ssh`.
+
+       To automatically update the wiki when you push changes to
+       `$REPOSITORY`, `ikiwiki` can install a `post-update` hook. You need to
+       enable this hook in `ikiwiki.setup` and the path to use should be
+       `$REPOSITORY/hooks/post-update`.
+
+       Finally, then, setup `ikiwiki`:
+
+                       ikiwiki --setup ikiwiki.setup
+
+       If you commit changes in `$SRCDIR`, make sure to `git push` them to
+       the `$REPOSITORY`.
