+The `polygen` directive is supplied by the [[!iki plugins/polygen]] plugin.
+
+This directive allows inserting text generated by polygen into a wiki page.
+For example:
+
+ \[[!polygen grammar="genius"]]
+
+It's also possible to specify a starting nonterminal for the grammar by
+including `symbol="text"` in the directive.
