-> Old config can be found in legacy branch
-
-### Installation
-
-1. Install [nix](https://nixos.org/download)
-2. Install [homebrew](https://brew.sh)
-3. Ensure Xcode command line tools are installed (setting up brew should already do this)
-4. Ensure you are signed into the App Store (when providing appids for `mas`)
-5. Clone this repository
-
-```sh
-git clone [email protected]:ecklf/dotfiles.git
-```
+## Darwin
 
-### Fresh Install
+### Setup 
 
 > [!TIP]
-> The macOS dock can be wiped with:
+> The Dock can be wiped with:
 > ```sh
 > defaults write com.apple.dock persistent-apps -array && killall Dock
 > ```
 
+**1: Install [nix](https://nixos.org/download) and [homebrew](https://brew.sh)**
+
+**2: Ensure Xcode command line tools are installed (setting up _homebrew_ should have already done this)**
+
+**3: Ensure you are signed into the App Store (if using app ids in `mas` configuration)**
+
+### Using this repository
+
 > [!IMPORTANT]  
-> For the very first run, `darwin-rebuild` won't be installed in your path.
+> For the very first run, `darwin-rebuild` won't be installed in your path
 > ```sh
 > nix run nix-darwin --extra-experimental-features flakes --extra-experimental-features nix-command -- switch --flake ~/dotfiles/nix#omega
 > ```
 
-### Usage
-
 ```sh
 # Build the flake `omega` (see flake.nix)
 darwin-rebuild build --flake ~/dotfiles/nix#omega
 # Switch to `omega` (see flake.nix)
 darwin-rebuild switch --flake ~/dotfiles/nix#omega
 ```
 
+## NixOS
+
+> [!NOTE]  
+> Also see the official guide:
+> https://nixos.wiki/wiki/NixOS_Installation_Guide
+
+### Setup
+
+**1: Download [ISO image](https://nixos.org/download/#nixos-iso), flash it to USB, and boot**
+
+**2: Setup Wireless (optional)**
+```sh
+sudo systemctl start wpa_supplicant
+wpa_cli
+> scan
+> scan_results
+> add_network
+> 0
+> set_network 0 ssid "NETWORK_SSID"
+> set_network 0 psk "NETWORK_SECRET"
+> enable_network 0
+> quit
+ip a
+ping google.com
+```
+
+**3: Partition Disks**
+
+These steps are for a UEFI system with GPT partitioning. Adjust as needed.
+
+> [!IMPORTANT]  
+> Ensure the label steps for `NIXROOT` and `NIXBOOT` are not skipped as they are used in the configuration.
+
+```sh
+# Identify disk
+lsblk # identify disk
+# Partition disk
+sudo fdisk /dev/sdX
+> g (gpt disk label)
+> n
+> 1 (partition number [1/128])
+> 2048 first sector
+> +500M last sector (boot sector size)
+> t
+> 1 (EFI System)
+> n
+> 2
+> default (fill up partition)
+> default (fill up partition)
+> w (write)
+# Identify partitions, label and make fs
+lsblk
+sudo mkfs.fat -F 32 /dev/sdX1
+sudo fatlabel /dev/sdX1 NIXBOOT
+sudo mkfs.ext4 /dev/sdX2 -L NIXROOT
+sudo mount /dev/disk/by-label/NIXROOT /mnt
+sudo mkdir -p /mnt/boot
+sudo mount /dev/disk/by-label/NIXBOOT /mnt/boot
+# Create swap file
+sudo dd if=/dev/zero of=/mnt/.swapfile bs=1024 count=2097152 (2GB size)
+sudo chmod 600 /mnt/.swapfile
+sudo mkswap /mnt/.swapfile
+sudo swapon /mnt/.swapfile
+```
+
+**4: Installation**
+```sh
+sudo nixos-generate-config --root /mnt
+cd /mnt
+sudo nixos-install
+```
+
+**5: Add nix channels**
+```sh
+# Add home-manager channel (update version if needed)
+sudo nix-channel --add https://github.com/nix-community/home-manager/archive/release-24.05.tar.gz home-manager
+sudo nix-channel --update
+```
+
+### Using this repository
+```sh
+# Build the flake `snowflake` (see flake.nix)
+sudo nixos-rebuild build --flake '~/dotfiles/nix#snowflake'
+# Switch to `snowflake` (see flake.nix)
+sudo nixos-rebuild switch --flake '~/dotfiles/nix#snowflake'
+```
+
+### Post Install
+
+> [!IMPORTANT]  
+> Update your user password
+> ```sh
+> sudo passwd
+> ```
+
+Set up Samba if used by configuration:
+
+```sh
+# See user info
+sudo pdbedit -L -v
+# Add samba password
+sudo smbpasswd -a $(whoami) 
+# Debug samba issues
+sudo systemctl status mnt-share.mount
+```
+
+## Updating inputs
+
 ```sh
 # Upgrading nix — https://nix.dev/manual/nix/2.22/installation/upgrading
-# Updating inputs
+# Updating flake inputs
 nix flake lock --update-all
 nix flake lock --update-input <input>
