 ## Requirements
 
-PGMS targets Windows x64. Building requires PowerShell 7 and a .NET 10 SDK compatible with [global.json](../../global.json): 10.0.400 with latest-patch roll-forward. Dependencies are pinned in NuGet lockfiles. The M1022 package was built with SDK 10.0.403 and bundles .NET/WPF 10.0.14; a rebuild may use different installed runtime packs.
