First, ensure that the necessary Google Cloud APIs are enabled for your project. To do this, follow the instructions on the [authentication document](https://github.com/GoogleCloudPlatform/gcloud-common/blob/master/authentication/readme.md#authentication) shared by all the gcloud language libraries.

Next, choose a method for authenticating API requests from within your project:

3. Before moving on, verify that the artifacts have successfully been pushed to the Maven Central Repository. Open Travis CI, click the ["Build History" tab](https://travis-ci.org/GoogleCloudPlatform/gcloud-java/builds), and open the second build's logs for Step 2's PR. Be sure that you are not opening the "Pull Request" build logs. When the build finishes, scroll to the end of the log and verify that the artifacts were successfully staged and deployed. You can also search for `gcloud-java` on the [Sonatype website](https://oss.sonatype.org/#nexus-search;quick~gcloud-java) and check the latest version number. If the deployment didn't succeed because of a flaky test, rerun the build.

4. Create a release on Github manually.

5. Run `utilities/update_pom_version.sh` again (to include "-SNAPSHOT" in the project version).

6. Create and merge in another PR to reflect the updated project version. For an example of what this PR should look like, see [#227](https://github.com/GoogleCloudPlatform/gcloud-java/pull/227).
