Use the following steps to get started using Nix and this configuration:

curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix | sh -s -- install macos  #The macos arguement was recently required to avoid encrypting the nix volume when filevault is already enabled.
git clone https://github.com/jbrockett/dotfiles.git
nix build github:jbrockett/dotfiles#homeConfigurations.jeremy.activationPackage
result/activate
home-manager switch --flake github:jbrockett/dotfiles#jeremy 

Other useful commands:

To upgrade all packages:

nix flake update
home-manager switch --flake .#jeremy

To clean up old derivations:

home-manager generations
home-manager remove-generations [generation ids]

To cleanup unused files:

nix-collect-garbage -d
