+is unlikely to happen any time soon), there's little we can do in this library.
+A work-around for this remains unknown.

+However this package does work on [`Windows Subsystem for Linux`](https://en.wikipedia.org/wiki/Windows_Subsystem_for_Linux) 
+(or WSL) without issues. We suggest [installing WSL](https://msdn.microsoft.com/en-us/commandline/wsl/install_guide) 
+when you want to run this package on Windows.
