Code Style

• I try to minimize imperative ways of coding when it comes to both producing the code and using the produced code
• for example, running multiple commands to install this and that
• I'm a big beliver on declarative programming and a big fan of relying on automated procedures
• that's also why there is a heavy usage on kustomize and fluxcd and even (optionally) nix
• I want tools to do the job for me because they are better at it
