Add option to disable alphabetical sorting and keep declaration order

[sebastienroux]

Hello,

By default values are sorted alphabetically.

It would be nice to be able to have the same order in the readme as the declarations in the values.yaml file.

Best regards,

What about --sort-values-order=file option?

Sorry i didn't saw this option, this feature already exists :)
