+
+## How Import Wranglers Work
+
+An "import wrangler" is a `default.nix` file that acts as a **local aggregator**, collecting all related configurations into one place for easy management. This pattern appears at multiple levels:
+
+### Level 1: Base System Configuration
+
+**File:** `modules/nixos/base/default.nix`
+
+```nix
+{ ... }:
+
+{
+  imports = [
+    ./nix.nix
+    ./boot.nix
+    ./networking.nix
+    ./users.nix
+    ./services.nix
+    ./programs.nix
+    ./graphics.nix
+    ./packages.nix
+  ];
+
+  system.stateVersion = "25.11";
+}
+```
+
+**Purpose:** Groups all foundational system configurations (boot, networking, users, services, packages) into a single import point. When you need to add a base system feature, you either:
+- Add it to an existing module file
+- Create a new module (e.g., `firewall.nix`) and add it to this import list
+
+**Benefits:**
+- Single import in `configuration.nix`: `./modules/nixos/base`
+- All base modules are in one place; easy to see what's included
+- New base modules are simply added to the imports list
+
+### Level 2: Environment-Specific System Configuration
+
+**Files:** `modules/nixos/i3wm/default.nix`, `modules/nixos/hyprland/default.nix`
+
+These are currently thin wrappers but follow the same pattern. To extend them (e.g., add environment-specific services or packages), you would create sub-modules:
+
+```nix
+# Example expansion of modules/nixos/i3wm/default.nix
+{ ... }:
+
+{
+  imports = [
+    ./xserver.nix        # X11-specific settings
+    ./i3.nix            # i3 window manager
+    ./keyboard.nix      # Czech keyboard layout
+  ];
+}
+```
+
+### Level 3: Home-Manager Orchestration
+
+**File:** `modules/home/i3wm/default.nix`
+
+```nix
+{ ... }:
+
+{
+  imports = [
+    ./dunst.nix
+    ./i3.nix
+    ./kitty.nix
+    ./neovim.nix
+    ./nnn.nix
+    ./picom.nix
+    ./polybar.nix
+    ./rofi.nix
+    ./scripts.nix
+    ./xdg.nix
+  ];
+}
+```
+
+**Purpose:** All i3wm-specific home-manager modules (dunst, i3 keybinds, polybar, etc.) are collected here. This is imported once in `mun.nix`, rather than importing 10 separate files.
+
+**Benefits:**
+- One line in `mun.nix`: `./modules/home/i3wm/default.nix`
+- All i3 home configs are clearly grouped
+- Easy to switch entire environments with a single comment/uncomment
+
+### Level 4: Multi-Rice Support (Hyprland)
+
+**File:** `modules/home/hyprland/default.nix`
+
+```nix
+{ ... }:
+
+{
+  imports = [
+    #./default.nix              # main hyprland rice (future)
+    ./chernobyl/default.nix     # chernobyl hyprland rice
+  ];
+}
+```
+
+**File:** `modules/home/hyprland/chernobyl/default.nix`
+
+```nix
+{ ... }:
+
+{
+  imports = [
+    ./dunst.nix
+    ./fastfetch.nix
+    ./hyprland.nix
+    ./kitty.nix
+  ];
+}
+```
+
+**Purpose:** Supports multiple visual rices/themes for the same window manager. The parent orchestrator selects which rice to use.
+
+**Benefits:**
+- Scale to many rices easily (add `./cyberpunk/default.nix`, `./nord/default.nix`, etc.)
+- Each rice has its own folder with consistent structure
+- Switch rices by commenting/uncommenting in the parent orchestrator
+
+---
+
+## Switching Environments
+
+### Switch from i3wm to Hyprland
+
+Edit **two files**:
+
+#### 1. System Configuration (`configuration.nix`)
+
+```nix
+{ config, lib, pkgs, ... }:
+
+{
+  imports = [
+    ./hardware-configuration.nix
+    ./modules/nixos/base
+    
+    # === Environment Choice ===
+    # Uncomment one of the following to select your environment:
+    #./modules/nixos/i3wm      # ← comment this
+    ./modules/nixos/hyprland   # ← uncomment this
+  ];
+}
+```
+
+#### 2. Home-Manager Configuration (`mun.nix`)
+
+```nix
+{ config, lib, pkgs, ... }:
+
+{
+  imports = [
+    #./modules/home/i3wm/default.nix      # ← comment this
+    ./modules/home/hyprland/default.nix   # ← uncomment this
+  ];
+  
+  # ... rest of mun.nix
+}
+```
+
+#### 3. Rebuild
+
+```bash
+sudo nixos-rebuild switch
+```
+
+---
+
+## Configuration Layers
+
+The configuration is organized in **four distinct layers**:
+
+### 1. **System-Wide Base (`modules/nixos/base/`)**
+
+Applied to **all environments**.
+
+**Includes:**
+- Nix settings (flakes, substituters)
+- Boot configuration (GRUB, EFI, kernel)
+- Networking (hostname, NetworkManager, Bluetooth)
+- Users (mun user definition)
+- System services (SSH, Pipewire, Printing, Ly display manager)
+- System programs (Firefox, Zsh, Java, Steam)
+- Graphics drivers (Intel VAAPI, hardware acceleration)
+- System packages (Neovim, Git, TeX Live, RetroArch, etc.)
+
+**Modify by:** Editing existing files in `base/` or creating new ones and adding them to `base/default.nix`.
+
+### 2. **Environment-Specific System (`modules/nixos/{i3wm,hyprland}/`)**
+
+Applied to **one environment at a time** (X11 vs Wayland).
+
+**i3wm includes:**
+- X11 enable
+- i3 window manager
+- Keyboard layout (Czech)
+- Display manager session
+
+**Hyprland includes:**
+- X11 disable
+- Hyprland enable
+- XDG portal for Wayland
+- Qt6 Wayland support
+- Keyboard layout (Czech)
+
+**Modify by:** Editing the respective `default.nix` or creating sub-modules.
+
+### 3. **Home-Manager User-Wide Config (`mun.nix`)**
+
+Configuration applied to user `mun` only.
+
+**Includes:**
+- SSH setup
+- Shell configuration (Zsh with oh-my-zsh)
+- Environment variables
+- Gnome-keyring service
+- User packages (Rust tools, Discord, utilities)
+- Environment-specific home-manager orchestrator import
+
+**Modify by:** Editing `mun.nix` directly or adding packages to the `packages` list.
+
+### 4. **Environment-Specific Home-Manager (`modules/home/{i3wm,hyprland}/`)**
+
+Applied to **one environment at a time**.
+
+**i3wm includes:**
+- i3 keybindings and layout
+- Polybar status bar
+- Dunst notifications
+- Picom compositor
+- Rofi launcher
+- NeoVim with LazyVim
+- Kitty terminal
+- Custom scripts
+- XDG MIME type defaults
+
+**Hyprland (chernobyl rice) includes:**
+- Hyprland config
+- Dunst notifications
+- Kitty terminal
+- Fastfetch system info
+
+**Modify by:** Editing the respective module files or adding new ones to the orchestrator `default.nix`.
+
+---
+
+## Modifying Configurations
+
+### Add a New System Package
+
+**File:** `modules/nixos/base/packages.nix`
+
+```nix
+environment.systemPackages = with pkgs; [
+  # ... existing packages ...
+  my-new-package  # ← add here
+];
+```
+
+### Add a New Base System Service
+
+**File:** `modules/nixos/base/services.nix` or create `modules/nixos/base/firewall.nix`
+
+If adding firewall rules, create a new file:
+
+```nix
+# modules/nixos/base/firewall.nix
+{ config, lib, pkgs, ... }:
+
+{
+  networking.firewall.allowedTCPPorts = [ 80 443 ];
+}
+```
+
+Then add to orchestrator:
+
+```nix
+# modules/nixos/base/default.nix
+{ ... }:
+
+{
+  imports = [
+    ./nix.nix
+    ./boot.nix
+    ./networking.nix
+    ./users.nix
+    ./services.nix
+    ./programs.nix
+    ./graphics.nix
+    ./packages.nix
+    ./firewall.nix  # ← add here
+  ];
+
+  system.stateVersion = "25.11";
+}
+```
+
+### Add an i3wm Home-Manager Module
+
+**File:** `modules/home/i3wm/my-new-config.nix`
+
+```nix
+{ config, pkgs, ... }:
+
+{
+  # Your home-manager config here
+}
+```
+
+Then add to orchestrator:
+
+```nix
+# modules/home/i3wm/default.nix
+{ ... }:
+
+{
+  imports = [
+    ./dunst.nix
+    ./i3.nix
+    # ... other modules ...
+    ./my-new-config.nix  # ← add here
+  ];
+}
+```
+
+### Add a New Hyprland Rice
+
+Create a new directory:
+
+```bash
+mkdir modules/home/hyprland/cyberpunk
+```
+
+Add files:
+
+```nix
+# modules/home/hyprland/cyberpunk/default.nix
+{ ... }:
+
+{
+  imports = [
+    ./dunst.nix
+    ./hyprland.nix
+    ./kitty.nix
+  ];
+}
+```
+
+Update parent orchestrator:
+
+```nix
+# modules/home/hyprland/default.nix
+{ ... }:
+
+{
+  imports = [
+    #./default.nix
+    ./chernobyl/default.nix
+    #./cyberpunk/default.nix  # ← uncomment to use
+  ];
+}
+```
+
+---
+
+## Rebuilding Your System
+
+After making changes:
+
+```bash
+# Switch to new system configuration
+sudo nixos-rebuild switch
+
+# Or, test first (doesn't activate)
+sudo nixos-rebuild test
+
+# Show what changed
+sudo nixos-rebuild dry-run
+```
+
+To edit and rebuild in one step:
+
+```bash
+# If you have the 'edit' alias from mun.nix
+edit
+sudo nixos-rebuild switch
+```
+
+---
+
+## Key Principles
+
+1. **One Import Per Layer:** Each `default.nix` orchestrator imports related modules, reducing clutter in parent files.
+
+2. **Separation of Concerns:** System config (nixos/) is separate from user config (home/); base is separate from environment-specific.
+
+3. **Easy Environment Switching:** Change environments by commenting one line in `configuration.nix` and `mun.nix`.
+
+4. **Scalability:** Adding new features (base services, home modules, rices) follows a consistent pattern of creating a file + adding it to the orchestrator.
+
+5. **Clarity:** Each file has a clear purpose; finding where to modify something is straightforward.
+
+---
+
+## Example Workflow
+
+### Goal: Add Firefox configuration to i3wm
+
+1. Create `modules/home/i3wm/firefox.nix`:
+   ```nix
+   { config, pkgs, ... }:
+
+   {
+     programs.firefox = {
+       enable = true;
+       profiles.mun = {
+         settings = {
+           "browser.startup.homepage" = "about:home";
+         };
+       };
+     };
+   }
+   ```
+
+2. Add to orchestrator in `modules/home/i3wm/default.nix`:
+   ```nix
+   imports = [
+     ./dunst.nix
+     ./firefox.nix  # ← add here
+     ./i3.nix
+     # ... rest
+   ];
+   ```
+
+3. Rebuild:
+   ```bash
+   sudo nixos-rebuild switch
+   ```
+
+Done! Firefox is now configured for the i3wm environment.
+
+---
+
+## Troubleshooting
+
+### "Module not found" error
+
+Check that all imports in `default.nix` files reference correct file paths. Use absolute paths from the module directory:
+- `./nix.nix` ✓ (correct)
+- `../base/nix.nix` ✓ (correct, relative to parent)
+- `/absolute/path/nix.nix` ✗ (avoid; use relative)
+
+### Environment not loading after switch
+
+Ensure **both** `configuration.nix` and `mun.nix` have the same environment enabled (not one i3wm and one hyprland).
+
+### Syntax errors in .nix files
+
+Use `nix flake check` to validate:
+```bash
+nix flake check
+```
