+[![Build Status](https://drone.data.coop/api/badges/nellemann/libcvrapi/status.svg)](https://drone.data.coop/nellemann/libcvrapi)
 ## Usage
 
-    CvrApi api = new CvrApi("My user agent", "mySecretToken");
-    Company company = api.getCompanyByVatNumber("57020415");
-    System.out.println(company.life.name);
+
+```java
+CvrApi api = new CvrApi("My user agent", "mySecretToken");
+Company company = api.getCompanyByVatNumber("57020415");
+System.out.println(company.life.name);
+```
 
 The *Company* represents most of the same properties as seen in the example JSON in the [api documentation](http://docs.rest.cvrapi.dk/).
