This repo provides a quick start to use the cumulus-library tool. You will need to create a credentials file and provide your aws_access_key_id and aws_secret_access_key. Once that is in place, you can use the ./start.sh to get the docker container up and running.
The startup script will mount /studies on the container to the studies folder in this repo. This should allow you to work with your study configurations and commit them to your repo easily.
