Microsoft.PowerShell.PlatyPS

PlatyPS is the tool that Microsoft uses to create the PowerShell content you get from Get-Help and build the content published as PowerShell documentation on Microsoft Learn.

PowerShell help files are stored as Microsoft Assistance Markup Language (MAML), an XML format. PlatyPS simplifies the authoring process by allowing you to write the help files in Markdown, then convert to MAML. Markdown is widely used in the software industry, supported by many editors including Visual Studio Code, and easier to author.

Microsoft.PowerShell.PlatyPS includes several improvements:

• Re-write in C# leveraging markdig for parsing Markdown (the same library used by Microsoft Learn to render Markdown)
• Provides a more accurate description of a PowerShell cmdlet and its parameters and includes information that was previously unavailable
• Creates an object model of the help file that you can manipulate and supports chaining cmdlets for complex operations
• Increased performance - processes 1000s of Markdown files in seconds

Install Microsoft.PowerShell.PlatyPS

PlatyPS runs on:

• Windows PowerShell 5.1+
• PowerShell 7+ on Windows, Linux, and macOS

Install the module from PSGallery.

Install-PSResource -Name Microsoft.PowerShell.PlatyPS

Getting started using PlatyPS

Creating help files with PlatyPS is a multi-step process:

1. Create new or update existing Markdown help files
2. Edit the Markdown help to add descriptions and examples
3. Test the Markdown help to ensure the files render correctly
4. Convert and publish the help files

For detailed guidance, see the PlatyPS documentation on Microsoft Learn.
