# yarn oprah import -s acg
Oprah: Stage  --> acg
Oprah: Config --> /Users/taylor/Documents/projects/src/acloudguru/cloud-optimization/aws/cost-and-usage/oprah.yml

For bug reports:

• What went wrong? I was unable to import parameters from a file generated by oprah export
• What did you expect should have happened? I should be able to run oprah export, then run oprah import using the same file.
• What was the config you used?

provider:
  name: ssm
