# 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
curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix | sh -s -- install
```
Launch a new shell. Then use Nix to switch to the macOS configuration:
```bash
sudo rm /etc/bashrc
sudo rm /etc/nix/nix.conf
2024-04-02 14:59:04 +00:00
export NIX_SSL_CERT_FILE="$HOME/Documents/t2-ca-bundle.pem"
nix \
--extra-experimental-features flakes \
--extra-experimental-features nix-command \
run nix-darwin -- switch \
--flake github:nmasur/dotfiles#lookingglass
```
Once installed, you can continue to update the macOS configuration:
```bash
darwin-rebuild switch --flake ~/dev/personal/dotfiles
```
