Installation (PowerShell Core)

Allows you to run PowerShell Core from a Linux or macOS host or even AWS Lambda .NET Core 2.1 runtime (as well on a Windows machine). Note that it is a significantly cut down environment from what you'd expect when running within a Windows OS. Part of the power of Windows PowerShell is that it makes anything that's exposed through the full .NET Framework is available to PowerShell, but much of this is specific to Windows. PowerShell Core is dependant on .NET Core, which is stripped down so that it can run on more platforms. This does cause some gotchas, for example cryptography is not available in .NET Core, therefore you can't create secure strings (which you'd normally use for handling passwords).
