    For questions just DM me on X: https://twitter.com/@m3tam3re
    There is also some NIXOS content on my YT channel: https://www.youtube.com/@m3tam3re

    One of the best ways to learn NIXOS is to read other peoples configurations. I have personally learned a lot from Gabriel Fontes configs:
    https://github.com/Misterio77/nix-starter-configs
    https://github.com/Misterio77/nix-config

    Please also check out the starter configs mentioned above.
