   Note that you have to enable the Google Cloud Datastore API on the [Google Developers Console][developers-console] before running the following commands.
   ```

   Here's an example run of `StorageExample`.
 
   Before running the example, go to the [Google Developers Console][developers-console] to ensure that Google Cloud Storage API is enabled and that you have a bucket.  Also ensure that you have a test file (`test.txt` is chosen here) to upload to Cloud Storage stored locally on your machine.
