-Note that for mercurial, the srcdir is converted into a mercurial
-repository. There is no need to have a separate repository with mercurial.
+For git, the `repo` is created as a bare git repository, and the srcdir is
+made into a clone of it. (monotone and darcs are similar.)
+
+For svn and cvs, the `repo` is the centralized repository, and the `srcdir`
+is a checkout of it.
+
+For for mercurial and bzr, the srcdir is the only repository set up.
+
+For darcs, the master repo's apply hook will be preconfigured to call a
+ikiwiki wrapper.
+
+Note that for monotone, you are assumed to already have run "mtn genkey"
+to generate a key.
+
+# EXAMPLE
+
+`ikiwiki-makerepo git /srv/web/wiki /srv/git/wiki.git/`
+
+This creates a bare repository `/srv/git/wiki.git/`,
+and sets up `/srv/web/wiki` to be a clone of it, committing
+any files that already exist in that directory.
