The psm1 uses powershell instead of pwsh

[kusuriya]

Just opening an issue for my pull request #12 , pwsh is the new name for powershell core and the name of the supported production binary on *nix systems. The new name should be embraced to make sure the module is not broken going forward.

Nice presentation at the summit BTW.

Thanks for the catch! Supporting running this module in PowerShell Core on Linux is hopefully in our future.
