+### PSScriptAnalyzer (Windows installer scripts)
+
+The PowerShell installer scripts under `installer/windows/` are linted with [PSScriptAnalyzer](https://github.com/PowerShell/PSScriptAnalyzer).
+
+Run the linter locally (requires PowerShell 5.1+ or PowerShell 7+):
+
+```powershell
+.\installer\windows\Run-Lint.ps1
+```
+
+The script will automatically install `PSScriptAnalyzer` from the PowerShell Gallery if it is not already present, then analyze every `.ps1` file in `installer/windows/` using the settings defined in `installer/windows/PSScriptAnalyzerSettings.psd1`.
+
+PSScriptAnalyzer runs in CI — the pipeline will fail if any issues are reported.
