SharePoint site design: PowerShell cmdlets
Site designs and site scripts have been released to production and are available for general use.
Use PowerShell cmdlets to create, retrieve, update, and remove site designs and site scripts to new and existing modern site collections.
To run the PowerShell cmdlets, you'll need to do the following:
