Hi @mscherer and @joesepi,

This is my first contribution to this repository. Could you please advise me on the process for getting PRs like this reviewed and merged? I appreciate your guidance.

Thank you!

Hi,

I would love to help, but I am not sure who is in charge of the more "editorial" decisions, I am taking care of making sure the website build, but anything above is not really my thing. From a quick look, the patch look correct, but as there was some focus on accessibility, I am not able to evaluate that part.

But I can let the CI run at minima. If no one answer here, I think you should get some attention from people on Slack.

Thanks, @mscherer.

I'll take care of the CI build error later today. It’s odd since I copied the code from similar blocks, but I’ll investigate and see what’s going on.

CI seems to just complain on the indentation, the link is not long enough to warrant a new line or something like that, see the previous link (the arxiv one) vs the documentation, (with href and classname on 1 line).
