-### Generate the name for a multi-tool container image
-
-When you want to use an image of a multi-tool container and you know the specific dependencies and their versions of that container, for example, by looking them up in the [BioContainers hash.tsv](https://github.com/BioContainers/multi-package-containers/blob/master/combinations/hash.tsv), you can use the `nf-core modules mulled` helper tool. This tool generates the name of a BioContainers mulled image.
