 # PSDesiredStateConfiguration module
 
+**NOTE: We are currently NOT accepting PRs for this project**
+
+**PSDesiredStateConfiguration** (DSC) is the PowerShell module that enables writing configuration as code.
+
+The DSC platform was originally built on top of WMI for Windows. Starting in PowerShell 7.1 and working
+with internal partner teams
+[Azure Guest Configuration](https://docs.microsoft.com/azure/governance/policy/concepts/guest-configuration)
+and [Automanage](https://azure.microsoft.com/services/azure-automanage), we started making
+DSC cross-platform by enabling `Invoke-DSCResource` to directly use resources without going through
+the Local Configuration Manager (LCM).
+
+Our initial cross-platform work to enable partner teams:
+
+- Separated out the DSC parts in the PowerShell engine and moved them as a subsystem into the
+  PSDesiredStateConfiguration module
+- Remove PSDesiredStateConfiguration module from the PowerShell 7 package. This allows the
+  PSDesiredStateConfiguration module to be developed independently of PowerShell and users can mix
+  and match versions of PowerShell and PSDesiredStateConfiguration for their environment.
+  - This is now available on the PowerShell Gallery: [PSDesiredStateConfiguration 2.x](https://www.powershellgallery.com/packages/PSDesiredStateConfiguration)
+- Removing the dependency on MOF: Initially, only support DSC Resources written as PowerShell
+  classes. This includes tooling to convert existing script based DSC Resources to be wrapped as
+  PowerShell classes.
+
+## Documentation and resources
+
+The documentation for **PSDesiredStateConfiguration** 3.0.0-beta1 is a work-in-progress. We invite the
+community to review the documentation and assist us as we work on new documentation during the platform
+development.
+
+For more information about DSC v3, see [PowerShell Desired State Configuration Overview](https://docs.microsoft.com/powershell/dsc/overview?view=dsc-3.0)
+
+To download the latest release from the PowerShell Gallery, see [PSDesiredStateConfiguration 3.0.0-beta1](https://www.powershellgallery.com/packages/PSDesiredStateConfiguration/3.0.0-beta1)
+
+## Community Feedback
+
+As we continue this journey to make DSC a cross-platform technology, we invite the community to
+share your ideas and open
+[issues](https://github.com/PowerShell/PSDesiredStateConfiguration/issues). During the PowerShell
+7.3 timeframe, we remain focused on enabling partner teams and will not be accepting public pull
+requests.
