+# DerGrumpfs Nix Configuration
+
+A unified Nix configuration for both NixOS and macOS using flakes, nix-darwin, and Home Manager.
+
+## About
+
+A single repository managing both machines declaratively with Nix. Shared home-manager configuration across platforms with platform-specific modules where needed.
+
+**Author:** Phil Keier
+
+## Machines
+
+| Hostname | Platform | Architecture |
+|----------|----------|--------------|
+| cyper-desktop | NixOS | x86_64-linux |
+| cyper-mac | macOS | x86_64-darwin |
+
+## Prerequisites
+
+### NixOS
+Nix is available out of the box. Enable flakes in your configuration.
+
+### macOS
+Install Nix using the [Determinate Systems installer](https://docs.determinate.systems/#products).
+
+**Note:** Homebrew is managed declaratively via nix-homebrew — if already installed it will auto-migrate, otherwise it is installed automatically.
+
+## Quick Start
+
+### Clone
+```bash
+git clone https://github.com/DerGrumpf/nix ~/.config/nix
+cd ~/.config/nix
+```
+
+### Customize
+
+Replace placeholders in `home/git.nix`:
+- `DerGrumpf` → your Git username
+- `p.keier@beyerstedt-it.de` → your Git email
+
+### Apply
+```bash
+# NixOS
+sudo nixos-rebuild switch --flake .#cyper-desktop
+
+# macOS
+darwin-rebuild switch --flake .#cyper-mac
+
+# Or after initial setup on either machine
+nix-switch
+```

+
+## Secrets
+
+Secrets are managed with [sops-nix](https://github.com/Mic92/sops-nix) and age encryption. The age key must be present at:
+
+- **Linux:** `~/.config/sops/age/keys.txt`
+- **macOS:** `~/.config/sops/age/keys.txt`
