+### Nix Setup
+> If you don't already have nix set up on your machine, follow this steps!
+
+#### Install nix
+```bash
+sh <(curl -L https://nixos.org/nix/install) --daemon
+```
+#### configure nix, adding some features that speed things up
+
+```bash
+mkdir -p ~/.config/nix/
+echo -e 'max-jobs = auto\nexperimental-features = nix-command flakes' > ~/.config/nix/nix.conf
+```
+#### configure global nix caches
+
+copy & paste the entire entry in your terminal:
+```bash
+sudo tee /etc/nix/nix.conf <<EOF
+build-users-group = nixbld
+substituters = https://cache.nixos.org/
+trusted-public-keys = cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY=
+EOF
+```
+
+#### _NOTE: restart your terminal here!_
+
+##### Install and configure direnv + nix-direnv
+
+```bash
+nix-env -i direnv nix-direnv
+echo  "source $HOME/.nix-profile/share/nix-direnv/direnvrc" >~/.direnvrc
+echo  "[[ -f ~/.bashrc ]] && . ~/.bashrc" >~/.bash_profile
+echo  'eval "$(direnv hook bash)"' >>~/.bashrc
+echo  'eval "$(direnv hook zsh)"' >>~/.zshrc
+```
+
+##### _NOTE: restart your terminal once more here!_
