+# SHORT DESCRIPTION
+
+Explanation of when & how to use `puppet.dsc` to convert private/internal PowerShell modules into Puppet modules.
+
+# LONG DESCRIPTION
+
+Sometimes you may want to puppetize a PowerShell module with DSC Resources which is _not_ published to the [Public PowerShell Gallery](https://www.powershellgallery.com/) - for any reason, but often because the resources include business-specific logic.
+
+Luckily, `Puppet.Dsc` makes no distinction between PowerShell modules with DSC Resources which are public and private; you just need to tell it _where_ to find the modules to Puppetize.
+
+The `New-PuppetDscModule` function is able to transparently use any valid PSRepository feed to retrieve PowerShell modules with DSC Resources:
+
+```powershell
+# To puppetize from an alternate PSRepository feed
+# Make sure to replace 'MyRepository' with your repository name
+New-PuppetDscModule -PowerShellModuleName PowerShellGet -PowerShellModuleVersion 2.2.3 -Repository MyRepository
+```
+
+If you don't already have a private PSRepository feed, you can [add one](https://docs.microsoft.com/en-us/powershell/scripting/gallery/how-to/working-with-local-psrepositories?view=powershell-7.1) via the Microsoft docs.
+You can even [register a PSRepository for a local or shared folder](https://docs.microsoft.com/en-us/powershell/scripting/gallery/how-to/working-with-local-psrepositories?view=powershell-7.1#registering-a-local-repository)!
+
+Once you have the repository added, you need to remember to specify the `Repository` parameter when calling `New-PuppetDscModule` - otherwise it will default to the [Public PowerShell Gallery](https://www.powershellgallery.com/).
