+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Repository Overview
+
+This is a NixOS configuration repository using flakes, managing multiple machines and home-manager configurations. The repository follows a modular architecture with reusable "roles" that can be composed for different machines.
+
+## Architecture
+
+### Flake Structure
+- **flake.nix**: Main entry point defining inputs (nixpkgs, home-manager, plasma-manager, etc.) and outputs for multiple NixOS configurations
+- **Machines**: `nix-book`, `boxy`, `wixos` (WSL configuration)
+- **Home configurations**: Standalone home-manager configuration for user `johno`
+
+### Directory Structure
+- `machines/`: Machine-specific configurations with hardware-configuration.nix
+- `roles/`: Modular system configurations (audio, bluetooth, desktop, users, etc.)
+- `home/`: Home Manager configurations and user-specific modules
+- `home/modules/`: User environment modules (emacs, i3+sway, plasma-manager, tmux)
+- `packages/`: Custom package definitions
+
+### Role-Based Configuration System
+The repository uses a custom "roles" system where each role is a NixOS module with enable options:
+- `roles.desktop`: Desktop environment with sub-options for X11, Wayland, KDE, gaming, SDDM
+- `roles.audio`: Audio configuration
+- `roles.bluetooth`: Bluetooth support
+- `roles.users`: User account management
+- `roles.virtualisation`: Virtualization setup
+- `roles.kodi`: Kodi media center
+
+Example role usage in machine configuration:
+```nix
+roles = {
+  audio.enable = true;
+  desktop = {
+    enable = true;
+    gaming = true;
+    kde = true;
+    wayland = true;
+  };
+  users.enable = true;
+};
+```
+
+## Common Commands
+
+### Building and Switching Configurations
+```bash
+# Build and switch to a specific machine configuration
+sudo nixos-rebuild switch --flake .#<hostname>
+
+# Build without switching
+nixos-rebuild build --flake .#<hostname>
+
+# Build home-manager configuration only
+home-manager switch --flake .#johno
+```
+
+### Available Machine Configurations
+- `nix-book`: Uses `home/home-nix-book.nix`
+- `boxy`: Gaming desktop with AMD GPU, uses `home/home.nix`
+- `wixos`: WSL configuration, uses `home/home.nix`
+
+### Flake Operations
+```bash
+# Update flake inputs
+nix flake update
+
+# Check flake
+nix flake check
+
+# Show flake info
+nix flake show
+```
+
+### Bootstrap New Machine
+Use the provided bootstrap script:
+```bash
+sudo ./bootstrap.sh <hostname>
+```
+This script pulls from the remote git repository and applies the configuration.
+
+## Development Workflow
+
+### Adding New Machines
+1. Create new directory in `machines/<hostname>/`
+2. Add `configuration.nix` with role assignments
+3. Include hardware-configuration.nix (generated by nixos-generate-config)
+4. Add nixosConfiguration to flake.nix outputs
+
+### Adding New Roles
+1. Create directory in `roles/<role-name>/`
+2. Create `default.nix` with module definition using mkEnableOption
+3. Add role import to `roles/default.nix`
+4. Configure role options in machine configurations
+
+### Home Manager Modules
+- Located in `home/modules/`
+- Each module has its own `default.nix`
+- Imported in main home configuration files
+
+## Key Configuration Details
+
+- **Experimental features**: nix-command and flakes are enabled
+- **User**: Primary user is `johno` with trusted-user privileges
+- **Locale**: en_US.UTF-8, America/Los_Angeles timezone
+- **SSH**: OpenSSH enabled on all configurations
+- **Garbage collection**: Automatic, deletes older than 10 days
+- **Unfree packages**: Allowed globally
