How to use the project check-config command

To facilitate this substantial config format change, starting with version 0.8.0 we introduced project check-config to sanity check your config files. From your project directory, run:

great_expectations --v3-api project check-config

This can be used at any time and will grow more robust and helpful as our internal config typing system improves.

You will most likely be prompted to install a new template. Rest assured that your original YAML file will be archived automatically for you. Even so, it's in your source control system already, right? ;-)
