 We use [CSharpGuidelines](https://csharpcodingguidelines.com/) as our coding standard (with a few minor exceptions). Coding style is validated during PR build, where we inject an extra settings layer that promotes various suggestions to warning level. This ensures a high-quality codebase without interfering too much when editing code.
 You can run the following [PowerShell scripts](https://github.com/PowerShell/PowerShell/releases) locally:
-- `pwsh inspectcode.ps1`: Scans the code for style violations and opens the result in your web browser.
-- `pwsh cleanupcode.ps1`: Reformats the entire codebase to match with our configured style.
+- `pwsh ./inspectcode.ps1`: Scans the code for style violations and opens the result in your web browser.
+- `pwsh ./cleanupcode.ps1 [branch-name-or-commit-hash]`: Reformats the codebase to match with our configured style, optionally only changed files since the specified branch (usually master).
 
 Code inspection violations can be addressed in several ways, depending on the situation:
 - Types that are reported to be never instantiated (because the IoC container creates them dynamically) should be decorated with `[UsedImplicitly(ImplicitUseKindFlags.InstantiatedNoFixedConstructorSignature)]`.
