quick start example runs into errors

[ameydhavle]

Using the quickstart guide and running the below command runs to error. Am I missing some confirguration. I have AWS CLI setup and all the aws cli commands work fine.
altimeter --base_dir /tmp/altimeter --regions us-east-1
usage: aws2json.py [-h] --config CONFIG output_dir
aws2json.py: error: the following arguments are required: --config

Thanks for the report! Documentation has been updated with the current usage.

Most options are now driven by a configuration file.

A sample config file conf/current_single_account.toml is probably what you'll want to try - this will scan the currently configured account:

altimeter --config conf/current_single_account.toml /tmp/altimeter
