+The `ymlfront` directive is supplied by the [[!iki plugins/contrib/ymlfront desc=ymlfront]] plugin.
+
+This directive allows the user to define arbitrary meta-data in YAML format.
+
+ \[[!ymlfront data="""
+ foo: fooness
+ bar: The Royal Pigeon
+ baz: 2
+ """]]
+
+There is one argument to this directive.
+
+* **data:**
+ The YAML-format data. This should be enclosed inside triple-quotes to preserve the data correctly.
+
+If more than one ymlfront directive is given per page, the result is undefined.
+Likewise, it is inadvisable to try to mix the "---" ymlfront format with the directive form of the data.
