+### Specify a relative path
+
+GitHub Actions doesn't support `working-directory` for `uses`, so you can't run this action separately for monorepo configuration, etc. However, if you specify the `RELATIVE` option, it will be used as `--relative=<RELATIVE>` for `git diff`.

+
+If the files `src/abc/test1.ts`, `src/abc/test2.ts`, `src/abc/test3.txt`, and `src/test4.ts` exist, the result will be as follows:

+```shell
