# SETTING UP A MACOS COMPUTER WITH NIX
# (flake edition)
# Stage 1: Getting nix
#
# sh <(curl -L https://nixos.org/nix/install) --daemon
#
# Stage 2: Getting nix-darwin 
#
# Install nix-darwin:
# 
#   $ nix-build https://github.com/LnL7/nix-darwin/archive/master.tar.gz -A installer
#   $ ./result/bin/darwin-installer
# 
# Stage 3: bootstrap
#  
#   $ nix build ~/.dotfiles\#darwinConfigurations.nyx.system
#   $ ./result/sw/bin/darwin-rebuild switch --flake ~/.dotfiles 
# 
# DONE!
# Now, every time you change the nix config:
# 
#   $ darwin-rebuild switch --flake ~/.dotfiles
# 
# And every now and then, update deps:
# 
#   $ nix flake update
#   $ nix flake lock --update-input <xyz>
