+
+[Data Catalog][datacatalog] is a fully managed and scalable metadata management service that empowers organizations
+to quickly discover, manage, and understand all their data in Google Cloud.
+This sample Java application demonstrates how to access the Data Catalog API using
+the [Google Cloud Client Library for Java][google-cloud-java].
+
+[datacatalog]: https://cloud.google.com/data-catalog/
+[google-cloud-java]: https://github.com/GoogleCloudPlatform/google-cloud-java
+
+## Quickstart
+
+#### Setup
+- Install [Maven](http://maven.apache.org/).
+- [Enable](https://console.cloud.google.com/apis/api/datacatalog.googleapis.com/overview) Data Catalog API.
+- Set up [authentication](https://cloud.google.com/docs/authentication/getting-started).
+
+#### Build
+- Build your project with:
+```
+  mvn clean package -DskipTests
+```
+
+#### Testing
+Run the test with Maven.
+```
+  mvn verify
+```
