+
+# Installation
+
+## NixOS
+
+1. Acquire a NixOS 24.05+ image:
+
+```bash
+wget -O https://channels.nixos.org/nixos-24.11/latest-nixos-minimal-x86_64-linux.iso
+```
+
+2. Write it to a USB drive. I prefer [Ventoy](https://www.ventoy.net/).
+3. Restart and boot into the installer.
+4. Clone these dotfiles somewhere and `cd` into them.
+```bash
+git clone https://github.com/x0ba/dotfiles.git
+```
+5. Set your desired encryption password.
+```bash
+echo -n "password" > /tmp/secret.key
+```
+6. Partition your disks using [disko](https://github.com/nix-community/disko). Make sure to replace the device arg with the hard disk you want to install NixOS on.
+```bash
+sudo nix --experimental-features "nix-command flakes" run github:nix-community/disko/latest -- --arg device '"/dev/nvme0n1"' --mode destroy,format,mount ./disks/default.nix
+```
+7. Create a host config in `systems`. See existing ones for examples.
+8. Install NixOS
+```bash
+sudo nixos-install --root /mnt --flake .#host
+```
+9. Reboot and you're good to go!
+10. [OPTIONAL] Set up an SSH key to decrypt sops secrets. Currently it's only being used to declaratively set my user password and for tailscale.
+
+## Darwin
+
+1. Install the XCode command line tools
+```bash
+sudo xcode-select --install
+```
+2. Install Homebrew.
+```bash
+/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
+```
+3. Install Nix using the [Determinate installer](https://github.com/DeterminateSystems/nix-installer).
+```bash
+curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix | \
+  sh -s -- install
+```
