2.1. GitHub SSH Key & Signing Key

1. Generate SSH key

```sh

ssh-keygen -t ed25519 -N "" -f ~/.ssh/github

```

1. Copy public key

```sh

# macOS

pbcopy < ~/.ssh/github.pub

# Linux

cat ~/.ssh/github.pub

```

1. Add SSH key to GitHub

- Key type: Authentication Key

- Paste the public key

1. Add Signing key to GitHub

3.1. Install Nix

```sh

sh <(curl --proto '=https' --tlsv1.2 -L https://nixos.org/nix/install)

```

Open a new terminal to verify:

```sh

nix --version

```

cf. [Nix Official Download](https://nixos.org/download/)

3.2. Clone dotfiles

Use nix run to temporarily get git

(no Command Line Developer Tools needed on macOS):

```sh

nix run nixpkgs#git -- clone git@github.com:i9wa4/dotfiles ~/ghq/github.com/i9wa4/dotfiles

cd ~/ghq/github.com/i9wa4/dotfiles

```

4.1. Backup Shell Configs

nix-darwin will fail if /etc/zshenv or /etc/zshrc exist

with unrecognized content.

```sh

sudo mv /etc/bashrc /etc/bashrc.before-nix-darwin 2>/dev/null || true

sudo mv /etc/zshrc /etc/zshrc.before-nix-darwin 2>/dev/null || true

```

cf. https://github.com/nix-darwin/nix-darwin/issues/149

4.2. Install Homebrew

nix-darwin manages Homebrew packages,

but Homebrew itself must be installed manually.

```sh

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

```

cf. [Homebrew](https://brew.sh/)

4.3. Initial darwin-rebuild

sudo nix --extra-experimental-features 'nix-command flakes' run nix-darwin -- switch --flake '.#macos-p' --impure --no-update-lock-file

```

or

```sh

sudo nix --extra-experimental-features 'nix-command flakes' run nix-darwin -- switch --flake '.#macos-w' --impure --no-update-lock-file

```

Open a new terminal after completion.
