1. there seems to be a couple of issue on the subject of natively using config files Add support for config files tj/commander.js#1584 (2021) & [Help] Struggling to implement configuration file options tj/commander.js#1843 (2023) although there is no super clear api like other cli frameworks.

Dans un premier temps, I'll make a straight forward implementation to identify the correct flow, logic and make sure we have all must have's. I will then procede to improve the code and prettify the cli output.
