 and ignore files starting with a period. To override this, use `-ln` flag to specify the shell dialect:
 `-ln posix` or `-ln bash`.
 
-NOTE: **Note:**
-Currently, the `shfmt` tool [is not shipped](https://github.com/mvdan/sh/issues/68) as a Docker image containing
-a Linux shell. This makes it impossible to use the [official Docker image](https://hub.docker.com/r/mvdan/shfmt)
-in GitLab Runner. This [may change](https://github.com/mvdan/sh/issues/68#issuecomment-507721371) in future.
