 ### Standalone
 
+You'll need [.NET 5 Runtime](https://dotnet.microsoft.com/download/dotnet/current/runtime) installed.
+
 If you don't want to use the installer, you can find the standalone version releases on GitHub [here](https://github.com/sleevezipper/hass-workstation-service/releases). Unpack all files to a folder and run `hass-workstation-service.exe`. This is the background service and you can use `UserInterface.exe` to configure the service. There is no automatic (or prompted) updating in the standalone version.

-- Registry - this is the preferred method. This will work from Windows 10 version 1903 and higher.
-- OpenCV - this method tries to access the webcam and if that fails, it assumes it is currently in use. This will flash the webcam activity light at every update interval. It also uses more CPU cycles and memory.

+### IdleTime
+
+This sensor returns the amount of seconds the workstation has been idle for. It starts counting the moment you stop typing or moving your mouse.

 ### Dummy
 
 This sensor spits out a random number every second. Useful for testing, maybe you'll find some other use for it.
