NixOS Configurations: `desktop` · `workstation` · `server` (wip) · `vm` · `wsl`
## Fresh Install 🚀
From the NixOS live installer:
```bash
# Enable flakes (not enabled by default on installer)
echo "experimental-features = nix-command flakes" | sudo tee -a /etc/nix/nix.conf
# Clone repo
nix run nixpkgs#git -- clone --recurse-submodules https://github.com/itme-brain/nixos.git
cd nixos
# Enter dev shell and install
nix develop
just install desktop
```
Replace `desktop` with `workstation` or `vm` as needed.
## Getting Started 🔧
```bash
