No description provided.

It's probably a good idea to add a reference to the training material that describes meta maps. This can be as easy as giving a one line description and linking to here at the appropriate position in the tutorial.

hi, is this now implemented?

@scheckley I can't find this anywhere, is this in the current version? Or a PR?

ah sorry, I should have posted the url with the screenshot. The screenshot is from here: https://nf-co.re/docs/contributing/tutorials/dsl2_modules_tutorial

I see. Sorry for not being clearer in my issue description. This is about including this reference in the new tutorial about nf-core tools that we are currently creating. We are trying to tie the different information source together somehow, which is why I would like to have a link to the meta map description added.

cool. happy to help with that.
