Description
docs/Quickstart.py says it will pop open a web browser window or tab at startup and prompt you for authentication to a bucket. It doesn't do that. It gives a failure to find credentials.json.
minor suggestion for improvement for step 4 is if it says that it cannot find credentials.json, to go back to step1 to generate it. Also, make sure that a web server is not running on the machine when you try this or it will fail with a socket error.
