+# @react-native-windows/find-dotnet-tools
+
+Helpers to locate .NET-based tools (e.g. PowerShell) restored via `dotnet tool restore` or
+available on PATH.
+
+Used to resolve tool paths consistently across local development and CI
+environments.
+
+## Usage
+
+Add the package as a dependency:
+
+```json
+{
+  "dependencies": {
+    "@react-native-windows/find-dotnet-tools": "<version>"
+  }
+}
+```
+
+### findPowerShell
+
+Locates a PowerShell executable by checking, in order:
+
+1. A `dotnet-tool`-restored copy of `pwsh.exe` (skipped in CI builds)
+2. `pwsh.exe` on the system PATH
+
+Throws an error if `pwsh.exe` cannot be found.
+
+```js
+import {findPowerShell} from '@react-native-windows/find-dotnet-tools';
+
+const pwsh = findPowerShell();
+// e.g. "C:\\Users\\user\\.nuget\\packages\\PowerShell\\7.6.1\\tools\\net10.0\\any\\win\\pwsh.exe"
+```
+
+### getNugetGlobalPackagesFolder
+
+Returns the path to the global NuGet packages folder by checking, in order:
+
+1. The `NUGET_PACKAGES` environment variable
+2. The output of `dotnet nuget locals global-packages --list`
+3. The default `~/.nuget/packages` location
+
+```js
+import {getNugetGlobalPackagesFolder} from '@react-native-windows/find-dotnet-tools';
+
+const packagesDir = getNugetGlobalPackagesFolder();
+// e.g. "C:\\Users\\user\\.nuget\\packages"
+```
