Package manager and OS focused on reproducible builds.
Zero to Nix is a guide for getting running and using nix. It uses an installer script by the publishing organization. I chose to use the official installer and activate flakes manually.

Enabling flakes
mkdir -p ~/.config/nix
echo "experimental-features = nix-command flakes" >> ~/.config/nix/nix.conf
Home Manager
Home manager allows you to configure your home environment (add tools and programs, and also configuring). This blog post lays out(Pedersen 2021) the basic ideas, but it was out of date in methodology by the time I tried. As of using the official guide got me on the right track. I experimented with the tool and got it working, ultimately, I don’t see a reason to replace my existing dotfiles / dotfile management with this. If I were starting out from scratch or very little configs, it may be worth it.
