Describe the bug

After installing via HACS i get an message saying that I should add via the UI (info.md).
But there isn't any integration called "average" or variations thereof that I can add with the UI.
The readme.md only documents installation via configuration.yaml. Which one is it?

Configuration.yaml

Add your configs here if any.
