 Netgen ContentType List Bundle
 ==============================
 
+[![Build Status](https://img.shields.io/travis/netgen/NetgenContentTypeListBundle.svg?style=flat-square)](https://travis-ci.org/netgen/NetgenContentTypeListBundle)
+
 Netgen ContentType List Bundle is an eZ Publish 5 bundle that provides a field type to select and store a list of content type identifiers.
 
 This repository represents eZ Publish 5 rewrite of the original eZ Publish 4 extension located at [http://github.com/netgen/ngclasslist](/netgen/ngclasslist). However, eZ Publish 4 extension is still required to populate field type through the admin interface.
