+Here's how to convert your existing standard format ikiwiki setup file into
+the new YAML format recently added to ikiwiki.
+
+1. First, make sure you have the [[!cpan YAML]] perl module installed.
+   (Run: `apt-get install libyaml-perl`)
+2. Run: `ikiwiki -setup my.setup -dumpsetup my.setup --set setuptype=Yaml`
+
+The format of the YAML setup file should be fairly self-explanatory.
