 # libcvrapi
 
+-----------------------------------
+
+A Java library to query with the Danish VAT API service <https://www.cvrapi.dk>. Work in progress.
+
+## Usage
+
+    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/).
