+# Microsoft's (internal) quickbuild
+
+Nerdbank.GitVersioning supports the Microsoft-internal quickbuild/cloudbuild tool.
+
+It works out of the box, but each project will recompute the version, which may accumulate to a significant increase in overall build time.
+
+🚧 A future version of Nerdbank.GitVersioning will cache version information as a file so that the following instructions will be effective. 🚧
+
+To calculate the version just once for an entire build, a few manual steps are required.
+
+1. Create this project in your repo. The suggested location is `VersionGeneration/VersionGeneration.msbuildproj`.
+
+    ```xml
+    <Project Sdk="Microsoft.Build.NoTargets">
+      <PropertyGroup>
+        <TargetFramework>net5.0</TargetFramework>
+        <IsPackable>false</IsPackable>
+        <SkipCopyBuildProduct>true</SkipCopyBuildProduct>
+        <NBGV_CacheMode>VersionGenerationTarget</NBGV_CacheMode>
+      </PropertyGroup>
+    </Project>
+    ```
+
+    The `TargetFramework` property value is not important as no assemblies are built by this project,
+    but a value is nonetheless required for NuGet to be willing to consume the Nerdbank.GitVersioning package reference
+    (which is referenced in Directory.Build.props as described later).
+
+1. Add the SDK version to your repo-root level `global.json` file, if it is not already present.
+    The [latest available version from nuget.org](https://www.nuget.org/packages/microsoft.build.notargets) is recommended.
+
+    ```json
+    {
+      "msbuild-sdks": {
+        "Microsoft.Build.NoTargets": "3.1.0"
+      }
+    }
+    ```
+
+1. Modify your repo-root level `Directory.Build.props` file to contain these elements:
+
+    ```xml
+    <PropertyGroup>
+      <!-- This entire repo has just one version.json file, so compute the version   once and share with all projects in a large build. -->
+      <GitVersionBaseDirectory>$(MSBuildThisFileDirectory)</GitVersionBaseDirectory>
+    </PropertyGroup>
+
+    <PropertyGroup Condition=" '$(QBuild)' == '1' ">
+      <NBGV_CacheMode>MSBuildTargetCaching</NBGV_CacheMode>
+      <NBGV_CachingProjectReference>$(MSBuildThisFileDirectory)VersionGeneration\VersionGeneration.msbuildproj</NBGV_CachingProjectReference>
+    </PropertyGroup>
+
+    <ItemGroup>
+      <PackageReference Include="Nerdbank.GitVersioning" Version="3.5.*" PrivateAssets="all" />
+    </ItemGroup>
+    ```
