## Detailed Description of the Pull Request / Additional comments

### Known bugs:
- Default settings not saving correctly when switching modes
- Issue: Sometimes when you switch from one mode to another, they are
supposed to update with new defaults but sometimes this fails for the
second variable. Potentially has to do with accessing the settings file
while another chunk of code is still updating.
- Sometimes the system looks "glitched" when switching themes

### To do:
- [x] OOBE page and assets
- [x] Logic to disable the chart when no location has been selected
- [x] Localization

### How to and what to test
Grab the latest installer from the pipeline below for your architecture
and install PowerToys from there.
- Toggle theme shortcutSystem only, Apps only, Both system and apps
selected
- Does changing the values on the settings page update the settings
file? %LOCALAPPDATA%/Microsoft/PowerToys/LightSwitch/settings.json
- Manual mode: System only, Apps only, Both system and apps selected
- Sunrise modes:  Are the times accurate?
- If you manage to let this run through sunset/rise does the theme
change?
- Set your theme to change within the next minute using manual mode and
set your device to sleepOpen your device and login once the time you set
has passed. --> Do your settings resync once the next minute ticks after
logging back into your device?
- Disable the service and ensure the tasks actually ends.
- While the module is disabled:
     - Make sure the shortcut no longer works
     - Make sure the last time you set doesn't trigger a theme change
- Bonus: Toggle GPO Configuration and make sure you are unable to enable
the module

-**✨Highlights**
+**✨ Highlights**
 
  - PowerToys Settings added a Settings search with fuzzy matching, suggestions, a results page, and UX polish to make finding options faster.
  - A comprehensive hotkey conflict detection system was introduced in Settings to surface and help resolve conflicting shortcuts. Note that the default hotkey settings (Win+Ctrl+Shift+T, Win+Ctrl+V, Win+Ctrl+T, Win+Shift+T) may overlap with existing Windows system shortcuts. This is expected. You can resolve the conflict by assigning different hotkeys.

+# Light Switch
+
+[Public Overview – Microsoft Learn](https://learn.microsoft.com/en-us/windows/powertoys/light-switch)
+
+## Quick Links
+
+* [All Issues](https://github.com/microsoft/PowerToys/issues?q=is%3Aissue%20state%3Aopen%20label%3AProduct-LightSwitch)
+* [Bugs](https://github.com/microsoft/PowerToys/issues?q=is%3Aissue%20state%3Aopen%20label%3AProduct-LightSwitch%20label%3AIssue-Bug)
+* [Pull Requests](https://github.com/microsoft/PowerToys/pulls?q=is%3Apr+is%3Aopen+label%3AProduct-LightSwitch)
+
+## Overview
+
+The **Light Switch** module lets users automatically transition between light and dark mode using a timed schedule or a keyboard shortcut.
+
+## Features
+
+* Set custom times to start and stop dark mode.
+* Use geolocation to determine local sunrise and sunset times.
+* Apply offsets in sunrise mode (e.g., 15 minutes before sunset).
+* Quickly toggle between modes with a keyboard shortcut (`Ctrl+Shift+Win+D` by default).
+* Choose whether theme changes apply to:
+
+  * Apps only
+  * System only
+  * Both apps and system
+
+## Architecture
+
+### Main Components
+
+* **Shortcut/Hotkey**
+  Listens for a hotkey event. Calling `onHotkey()` flips the theme flags.
+
+  > **Note:** Using the shortcut overrides the current schedule until the next transition event.
+
+* **LightSwitchService**
+  Reads settings and applies theming. Runs a check every minute to ensure the state is correct.
+
+* **SettingsXAML/LightSwitch**
+  Provides the settings UI for configuring schedules, syncing location, and customizing shortcuts.
+
+* **Settings.UI/ViewModels/LightSwitchViewModel.cs**
+  Handles updates to the settings file and communicates changes to the front end.
+
+* **modules/LightSwitch/Tests**
+  Contains UI tests that verify interactions between the settings UI, system state, and `settings.json`.
+
+### Data Flow
+
+1. User configures settings in the UI (default: manual mode, light mode from 06:00–18:00).
+2. Every minute, the service checks the time.
+
+   * If it’s not a threshold, the service sleeps until the next minute.
+   * If it matches a threshold, the service applies the theme based on settings and returns to sleep.
+3. At **midnight**, when in *Sunrise to Sunset* mode, the service updates daily sunrise and sunset times.
+4. If the machine was asleep during a scheduled event, the service applies the correct settings at the next check.
+
+## User Interface
+
+The module’s settings are exposed in the PowerToys Settings UI. Options include:
+
+* Shortcut customization
+* Mode selection (Manual or Sunrise to Sunset)
+* Manual start/stop times (manual mode only)
+* Automatic sunrise/sunset calculation (location-based)
+* Time offsets (sunrise mode)
+* Target scope (system, apps, or both)
+
+## Development Environment Setup
+
+### Prerequisites
+
+* Visual Studio 2019 or later
+* Windows 10 SDK
+* PowerToys repository cloned from GitHub
+
+### Building and Testing
+
+1. Clone the repo:
+
+   ```sh
+   git clone https://github.com/microsoft/PowerToys.git
+   ```
+2. Initialize submodules:
+
+   ```sh
+   git submodule update --init --recursive
+   ```
+3. Build the solution:
+
+   ```sh
+   msbuild -restore -p:RestorePackagesConfig=true -p:Platform=ARM64 -m PowerToys.sln
+   ```
+
+   > Note: This may take some time.
+4. Set `runner` as the startup project and press **F5**.
+5. Enable Light Switch in PowerToys Settings.
+6. To debug the service:
+
+   * Press `Ctrl+Alt+P` or go to **Debug > Attach to Process**.
+   * Select `LightSwitchService.exe` and click **Attach**.
+   * You can now set breakpoints in the service files.
+7. To debug the Settings UI:
+
+   * Set the startup project to `PowerToys.Settings` and press **F5**.
+   * Note: Light Switch settings will not persist in this mode (they depend on the service executable).
+   * Alternatively, you can attach `PowerToys.Settings.exe` to the debugger while `runner` is running to test the full flow with breakpoints.
