 ## Prerequisites
 
-When you have PowerShell 5 on your client machine, the PSVersion entry in `$PSVersionTable` reads 5.0... and PackageManagement is there implicitly.
-When you have a PowerShell version lower than 5 on your client machine, the PSVersion entry in `$PSVersionTable` reads 4.0 or even 3.0. Note that the latest Knowledge Center 2016SP1/12.0.1 release is only verified with PowerShell 4 (not 5 or above), so don't upgrade your servers. As ISHRemote is about a client-side web services driven library I actually don't expect you to even install it on a server.

+Note that we rely on `Windows PowerShell` (FullCLR), and not `PowerShell Core` (CoreCLR) which relies on `.NET Core`. Main reason is that the Core edition doesn't offer all supporting libraries for `WS-Trust` based authentication like `System.IdentityModel` and `System.ServiceModel`.
 
 ## Install
 Open a PowerShell, then you can find and install the ISHRemote module. CurrentUser `-Scope` indicates that you don't have to run PowerShell as Administrator. The `-Force` will make you bypass some security/trust questions.
