 The tool is useful for scenarios where you need to programmatically change the resolution of a display, for example, 
 during "do" and "undo" commands run as part of a [Moonlight](https://moonlight-stream.org/) session via [Sunshine](https://github.com/LizardByte/Sunshine).
 
 These examples assume the application is installed at `C:\Program Files\ResolutionSwitcher\ResolutionSwitcher.exe`.
