YAML syntax
YAML is a human friendly language for the communication of data between people and computers. The language is rich enough to represent almost any conceivable data structure or object inside a running computer program, as a readable plain text file. This type of language is often called a “serialization language” and YAML is definitely one of those. But unlike most serialization languages, the YAML format tries hard to make simple things really simple.
This is how the YAML data project puts it, and it's spot on. Thus, for anything where we need configuration files that should be readable by both humans and machines, we use the YAML language.

For a very strict yaml linter, check out yamllint.
It is available via the conda-forge channel, so you can install it into its own yamllint conda/mamba evnironment with:
mamba create -n yamllint yamllint
