 Libero JATS support
 ===================
 
+[![Build Status](https://travis-ci.com/libero/jats-support.svg?branch=master)](https://travis-ci.com/libero/jats-support)
+
+The library contains [Schematron](http://schematron.com/) that can be applied to any [Journal Article Tag Suite
+ (JATS)](https://jats.nlm.nih.gov/) document to check for native support in [Libero](https://libero.pub).
+ 
+It uses [XSLT 1.0](https://www.w3.org/TR/1999/REC-xslt-19991116) so that it is compatible with
+[libxslt](http://xmlsoft.org/XSLT/intro.html), and so natively supported by languages such as PHP and Python.
+ 
+Getting started
+---------------
+
+Apply [`src/support.sch`](src/support.sch) to your document, using, for example:
+
+- [Oxygen XML Editor](https://www.oxygenxml.com/demo/Schematron_Validation.html)
+- [XML Validator library](https://github.com/libero/xml-validator) (PHP)
+- [lxml](https://lxml.de/validation.html#id2) (Python)
+
