 Automatic update of SAML 2.0 Metadata XML from HTTPS
 ----------------------------------------------------
 
-simpleSAMLphp supports the SAML 2.0 Metadata XML format. There are mulitple ways of using simpleSAMLphp with SAML 2.0 Metadata XML documents, but the reccomended approach is to use the command line utility `bin/parseMetadata.php` to download and parse metadata from a HTTPS location. This script will grab the XML document from a URL and parse the content and output simpleSAMLphp flat files in a directory. In the `config.php` configuration you should configure simpleSAMLphp to read these files generated by `parseMetadata.php`.
+The `metarefresh` module is the preferred method for doing this.
+Please see the [metarefresh documentation](http://rnd.feide.no/content/automated-metadata-distribution-with-simplesamlphp).
