+# Base Desktop Environment Configuration
+
+This directory contains base configurations for Linux desktop environments, providing essential
+components for a complete Wayland desktop experience.
+
+## Overview
+
+The configuration is organized into modular components that can be selectively enabled:
+
+- **Desktop Shell**: Noctalia Shell for unified desktop environment
+- **Applications**: Desktop tools, browsers, editors, media players, etc.
+- **Development Tools**: IDEs and development utilities
+- **System Integration**: Input methods, theming, XDG specifications, GPU settings
+
+## Noctalia Shell
+
+**Noctalia Shell** is an all-in-one Wayland desktop shell that replaces multiple separate tools with
+a single, unified solution. It provides:
+
+- **Unified Configuration**: All components configured in a single `settings.json` file
+- **Consistent Experience**: Cohesive visual design and interaction patterns
+- **Reduced Complexity**: No need to maintain multiple separate config files
+
+### Component Replacement
+
+Noctalia Shell consolidates functionality that previously required multiple tools:
+
+| Traditional Component  | Purpose              | Noctalia Replacement           |
+| ---------------------- | -------------------- | ------------------------------ |
+| **gammastep**          | Blue light filter    | `nightLight` configuration     |
+| **swaylock**           | Screen locker        | Built-in lock screen           |
+| **anyrun**             | Application launcher | `appLauncher`                  |
+| **mako**               | Notification daemon  | `notifications`                |
+| **waybar**             | Status bar           | `bar` (with widgets)           |
+| **wallpaper-switcher** | Wallpaper management | `wallpaper` (with transitions) |
+| **wlogout**            | Session menu         | `sessionMenu`                  |
+| **wl-clipboard**       | Clipboard management | Built-in clipboard manager     |
