 You can define your own formatting rules in a `.clang-format` file at your repository root, or you can provide a fallback style (see [`fallback-style`](#inputs)). You can also provide a path to check. If you want to run checks against multiple paths in your repository, you can use this Action in a [matrix run](#multiple-paths).
