+# NixOS Gaming Base
+
+Diese Basis-Config ist fuer ein Desktop-System mit
+
+- Intel Core i9-13900KF
+- AMD Radeon RX 9070 XT
+
+ausgelegt und nutzt jetzt `nixos-unstable`, `Chaotic-Nyx` und COSMIC als Wayland-Desktop. Fokus:
+
+- aktueller Kernel
+- AMD-Grafik mit Chaotic `mesa-git` und 32-Bit-Libs fuer Steam/Proton
+- PipeWire + Gaming-/Desktop-Audio-Tools
+- Steam, Gamescope, MangoHud, Lutris, Heroic, LACT
+- RGB- und Peripherie-Basis fuer deine USB-Geraete
+
+## Struktur
+
+- `flake.nix`: Einstieg ueber `nixos-unstable` + `chaotic-cx/nyx`
+- `configuration.nix`: Host-spezifische Einstiegsdatei
+- `modules/base.nix`: Boot, Kernel, Locale, Nix, Firmware, Governor
+- `modules/chaotic-nyx.nix`: Chaotic-Nyx Aktivierung, `allowUnfree`, `mesa-git`
+- `modules/graphics/mesa-amd.nix`: AMDGPU + Mesa/RADV Basis
+- `modules/audio/pipewire.nix`: PipeWire, JACK, Pulse, Audio-Tools
+- `modules/gaming.nix`: Steam, Gamescope, Wine/Launcher-Stack
+- `modules/desktop/cosmic.nix`: COSMIC Desktop + COSMIC Greeter
+- `modules/peripherals.nix`: OpenRGB, Logitech/Corsair-nahe Tools, USB-Helfer
+
+## USB-Bezug
+
+Die Config beruecksichtigt diese aktuell erkannten Geraete:
+
+- `048d:5702` ITE RGB LED Controller
+- `1235:8211` Focusrite Scarlett Solo 3rd Gen
+- `1b1c:1bfd` Corsair K70 CORE RGB
+- `046d:c539` Logitech Lightspeed Receiver
+
+Daraus folgen aktuell:
+
+- `openrgb` + `hardware.i2c.enable` fuer RGB-/Board-Zugriff
+- `ratbagd` + `piper` fuer Logitech-Gaming-Peripherie
+- `solaar`, `usbutils`, `pciutils` fuer Device-Handling und Diagnose
+- PipeWire-Setup fuer das Scarlett Solo
+- COSMIC als Wayland-Desktop mit `cosmic-greeter`
+- Chaotic `mesa-git` mit Fallback-Spezialisierung `stable-mesa`
+
+## Chaotic-Nyx Hinweis
+
+Die Flake bindet `github:chaotic-cx/nyx/nyxpkgs-unstable` direkt ein und importiert
+`chaotic.nixosModules.default`.
+`modules/chaotic-nyx.nix` aktiviert `chaotic.mesa-git.enable = true;`.
+
+## Nach der Installation
+
+1. Die vom Installer erzeugte `hardware-configuration.nix` nach `./hardware-configuration.nix` kopieren.
+2. Falls noetig `users.users.max` und `networking.hostName` in `configuration.nix` anpassen.
+3. Passwort fuer den Benutzer setzen:
+
+```bash
+passwd max
+```
+
+4. Flake lock erstellen:
+
+```bash
+nix flake lock
+```
+
+5. System aktivieren:
+
+```bash
+sudo nixos-rebuild switch --flake .#nixos-gaming
+```
+
+## Spaeterer Ausbau
+
+- COSMIC weiter tunen, z. B. Autologin, Keyring-Policy, Flatpak
+- OBS / Discord / OpenRGB-Profile / Fancontrol
+- Btrfs-Subvolumes, Snapshots, Impermanence
+- spezielle Kernel- oder Scheduler-Tweaks, falls du sie wirklich brauchst
