# Installation
## NixOS - From Live Disk
Format drives and build system from any NixOS host, including the live
installer disk:
**This will erase your drives; use at your own risk!**
```bash
lsblk # Choose the disk you want to wipe
nix-shell -p nixVersions.stable
nix run github:nmasur/dotfiles#installer -- nvme0n1 tempest
```
## NixOS - From Existing System
If you're already running NixOS, you can switch to this configuration with the
following command:
```bash
nix-shell -p nixVersions.stable
sudo nixos-rebuild switch --flake github:nmasur/dotfiles#tempest
```
## Windows - From NixOS WSL
After [installing NixOS on
WSL](https://xeiaso.net/blog/nix-flakes-4-wsl-2022-05-01), you can switch to
the WSL configuration:
```
nix-shell -p nixVersions.stable
sudo nixos-rebuild switch --flake github:nmasur/dotfiles#hydra
```
You should also download the
[FiraCode](https://github.com/ryanoasis/nerd-fonts/releases/download/v2.2.2/FiraCode.zip)
font and install it on Windows. Install [Alacritty](https://alacritty.org/) and
move the `windows/alacritty.yml` file to
`C:\Users\<user>\AppData\Roaming\alacritty`.
## macOS
To get started on a bare macOS installation, first install Nix:
```bash
sh -c "$(curl -L https://nixos.org/nix/install)"
```
Then use Nix to build nix-darwin:
```bash
nix-build https://github.com/LnL7/nix-darwin/archive/master.tar.gz -A installer
./result/bin/darwin-installer
```
Then switch to the macOS configuration:
```bash
darwin-rebuild switch --flake github:nmasur/dotfiles#lookingglass
```
