4. Enable object versioning in your bucket using the command gsutil versioning set on gs://your-bucket-name.
5. In your Ruby code, require gcslock/mutex and use it as follows:

require 'gcslock/mutex'

m = GCSLock::Mutex.new('your-bucket-name', 'my-file.lock')
m.synchronize do
  // Protected and globally serialized computation happens here.
end
