-Clone the repository, `cd` to it, adapt the paths in the build.xml to match your system and run `ant -v`.
+. Clone the repository, `cd` to it:
+. Run `ant -v -DinputFile=file:<path_to_saml_metadata_file>`
+
+By default, if `-DinputFile=file:<path_to_saml_metadata_file>` is not specified, `ant -v` will assess the metadata quality of the https://raw.githubusercontent.com/clarin-eric/SPF-SPs-metadata/master/clarin-sp-metadata.xml[the main CLARIN SPF metadata file]. This default is defined in build.xml#L34[build.xml]

 == Use cases
 
-The SAML metadata QA validator is currently used by the CI system of the https://github.com/clarin-eric/SPF-SPs-metadata[CLARIN SPF-SPs-metadata repository] to automacticaly generate its https://clarin-eric.github.io/SPF-SPs-metadata/page/master_qa_report.html[QA assessment report] on every commit.

 This aids CLARIN SP operators and managers, to access the quality and conformance of their metadata with the https://www.clarin.eu/content/guidelines-saml-metadata-about-your-sp[CLARIN SPF metadata guidelines], uppon submmition of their SAML metadata to the repository. It also helps the CLARIN SPF operators to make recomendations and acceptance decisions.
