+[![image size](https://ghcr-badge.egpl.dev/articola-tools/dockerfile-linter/size?color=dodgerblue)](https://ghcr-badge.egpl.dev/articola-tools/dockerfile-linter/size?color=dodgerblue)

+Use `ghcr.io/articola-tools/dockerfile-linter` Docker image with `-v ./:/linter_workdir/repo`
+parameter, where `./` - is a path to a folder with files you want to lint.
+
+Example command to use this linter -
+`docker run --rm -v ./:/linter_workdir/repo ghcr.io/articola-tools/dockerfile-linter`
