+# NixOS Starter for Raspberry Pi 4
+
+A declarative NixOS flake setup for Raspberry Pi 4, following a modular configuration structure.

+```
+
+## Quick Start
+
+### 1. Flash NixOS to SD Card
+
+```bash
+# Download aarch64 image
+wget https://hydra.nixos.org/build/XXXXX/download/1/nixos-sd-image-aarch64-linux.img.zst
+
+# Flash to SD card (replace sdX with your device)
+zstdcat nixos-sd-image-aarch64-linux.img.zst | sudo dd of=/dev/sdX bs=4M conv=fsync
+```
+
+### 2. Boot and Setup Network
+
+Boot the RPi 4 and find its IP address:
+
+```bash
+arp-scan -l
+ssh root@<ip>  # Default password is empty
+```
+
+### 3. Clone Configuration
+
+```bash
+cd /tmp
+git clone <your-repo> nixos-config
+cd nixos-config
+```
+
+### 4. Apply Configuration
+
+```bash
+# Switch to new configuration
+sudo nixos-rebuild switch --flake .#rpi-4
+```
+
+## Customization
+
+### Change Username
+
+Edit `flake.nix`:
+```nix
+primaryUser = "your-username";  # Change from "phil"
+```
+
+### Add System Packages
+
+Edit `nixos/packages.nix`:
+```nix
+environment.systemPackages = with pkgs; [
+  # ... existing packages ...
+  python3
+  nodejs
+];
+```
+
+### Add User Packages
+
+Edit `home/packages.nix`:
+```nix
+home.packages = with pkgs; [
+  # ... existing packages ...
+  poetry
+  nodePackages.pnpm
+];
+```
+
+### Configure Git
+
+Edit `home/git.nix`:
+```nix
+programs.git = {
+  enable = true;
+  userName = "Your Name";
+  userEmail = "your@email.com";
+  # ... more config
+};
+```
+
+### Customize Shell
+
+Edit `home/shell.nix` for Zsh, Tmux, and Starship customizations.
+
+### Add Host-Specific Settings
+
+Edit `hosts/rpi-4/configuration.nix` for RPi 4-specific packages and settings.
+
+## Available Commands
+
+```bash
+# Rebuild and switch to new configuration
+rebuild
+
+# Build without switching
+rebuild-build
+
+# Show system health (disk, memory, CPU, temp)
+sys-health
+
+# SSH into RPi
+ssh-rpi [user] [host]
+
+# Update flake inputs
+flake-update
+
+# Show largest directories
+du-top
+```
+
+To use these commands, source the shell functions:
+
+```bash
+source hosts/rpi-4/shell-functions.sh
+```
+
+Or add to your zsh config to load automatically.
+
+## Configuration Files Overview
+
+### flake.nix
+- Declares inputs (nixpkgs, home-manager, etc.)
+- Defines outputs and system configuration
+- Entry point for the entire setup
+
+### nixos/default.nix
+- Main NixOS system configuration
+- Imports hardware, settings, and packages modules
+- Configures SSH, users, Nix settings
+
+### nixos/hardware.nix
+- RPi 4 bootloader and kernel settings
+- Filesystem and swap configuration
+- RPi 4-specific hardware enablement
+
+### nixos/settings.nix
+- Timezone and locale settings
+- Console keyboard layout
+- General system preferences
+
+### nixos/packages.nix
+- System-level packages available to all users
+
+### home/default.nix
+- Home Manager entry point
+- Imports shell, git, and packages modules
+- Sets home state version
+
+### home/packages.nix
+- User-level packages
+
+### home/git.nix
+- Git configuration (name, email, core settings)
+
+### home/shell.nix
+- Zsh configuration (aliases, keybindings, plugins)
+- Tmux configuration (prefix, keybindings)
+- Starship prompt setup
+- Direnv integration
+
+### hosts/rpi-4/configuration.nix
+- Host-specific package additions
+- RPi 4-specific customizations
+
+### hosts/rpi-4/shell-functions.sh
+- Bash functions for common tasks
+- Can be sourced in shell configs
+
+## Locale and Timezone
+
+Default settings:
+- **Timezone**: Europe/Berlin
+- **Locale**: en_US.UTF-8 (with German regional settings)
+
+Change in `nixos/settings.nix`:
+
+```nix
+time.timeZone = "America/New_York";
+i18n.defaultLocale = "en_US.UTF-8";
+```
+
+## Troubleshooting
+
+### SSH Connection Issues
+- Ensure SSH is enabled in `nixos/default.nix`
+- Check public key is authorized
+- Verify hostname resolves: `ping rpi-4.local`
+
+### Out of Memory
+Increase swap in `nixos/hardware.nix`:
+
+```nix
+swapDevices = [{
+  device = "/swapfile";
+  size = 4096;  # Increase to 4GB
+}];
+```
+
+### Package Not Found
+```bash
+# Search for a package
+nix search nixpkgs package-name
+
+# Add to appropriate .nix file and rebuild
+```
+
+### Rebuild Fails
+```bash
+# Update flake inputs
+nix flake update
+
+# Check for errors
+nix flake check
+```
+
+## Useful Nix Commands
+
+```bash
+# Update all inputs to latest versions
+nix flake update
+
+# Check flake for errors
+nix flake check
+
+# Show flake outputs
+nix flake show
+
+# Search for packages
+nix search nixpkgs <n>
+
+# Inspect package
+nix eval -f '<nixpkgs>' 'hello.meta.description'
+```

+- [RPi NixOS Guide](https://nixos.wiki/wiki/NixOS_on_ARM/Raspberry_Pi)
+
+## Notes
+

+- Store auto-optimizes weekly and cleans packages older than 30 days
+- Flakes and nix-command are enabled by default
+- Change `primaryUser` from "phil" to your username
