Home Manager is a system for managing a user environment using the Nix package manager. In other words, Home Manager lets you
- install software declaratively in your user profile, rather than using nix-env
- manage dotfiles in the home directory of your user.
Home Manager has many options, which can look daunting at first, but most of those options only boil down to creating some dotfile and installing some software in a way similar way to nix-env.
