Google maintains documentation on getting started here: https://cloud.google.com/storage/docs/quickstart-console
Getting ready to use GCS:
- Create a Google Cloud project, if you don't have one already.
- Enable billing for your project to allow buckets to be created.
- (Optional) Install the Google Cloud SDK, which includes gsutil, GCS's command line utility. As an alternative, you can use gsutil directly from the Google Cloud UI by using the Google Cloud Shell.
