+> **Important:**
+> This repository will be retired by the end of 2020. As of the GA of the Cross-Platform [PnP.PowerShell](https://github.com/pnp/pnp.powershell) we will only maintain that version going forward.
 
-### Prerequisites ###
-In order to generate the Cmdlet help you need to have the Windows Management Framework v4.0 installed, which you can download from http://www.microsoft.com/en-us/download/details.aspx?id=40855

-If it is not [pre-installed on your operating system](https://docs.microsoft.com/powershell/scripting/wmf/overview#wmf-availability-across-windows-operating-systems), you can find installation instructions in the [WMF release notes.](https://docs.microsoft.com/powershell/scripting/wmf/overview#wmf-release-notes)

-### Latest Release Quick Download
+Between now and the end of 2020 both [PnP-PowerShell](https://github.com/pnp/pnp-powershell) and [PnP.PowerShell](https://github.com/pnp/powershell) are actively maintained. Once the new PnP PowerShell becomes generally available (GA) we will stop mainting the old repository.
 
-The latest release can be found on [this link](https://github.com/pnp/PnP-PowerShell/releases)
+Given that the cross-platform PnP PowerShell is our future going forward we would prefer issues and PRs being created in the new https://github.com/pnp/powershell repository. If you want your PR to apply to both then it is recommend to create the PR in both repositories for the time being.
