-
-## Run shellcheck only in a single directory
-
-If you have multiple directories with scripts, but only want to scan
-one of them, you can use the following configuration:
-
-```yaml
-   ...
-   - name: Run ShellCheck
-     uses: ludeeus/action-shellcheck@master
-     with:
-       scandir: './scripts'

-If you need to scan for unusual files, you can use the `additional_files` key.

-     with:
-       additional_files: 'run finish'
-```
-
-## Change output format
-
-Shellcheck can print output in these formats: `checkstyle`, `diff`, `gcc`, `json`, `json1`, `quiet`, `tty`. See some examples [here](https://github.com/koalaman/shellcheck/wiki/Integration#pick-the-output-format-that-makes-your-life-easier).
-
-- `tty` has multi-line log messages
-- `gcc` has single-line log messages

-
-## Run a specific version of Shellcheck
-
-If running the latest stable version of Shellcheck is not to your liking, you can specify a concrete version of Shellcheck to be used. When specifying a custom version, please use any of the released versions listed in the [Shellcheck repository](https://github.com/koalaman/shellcheck/tags).
