Hello,
I am new to this, apologies. The tests failed, and then I was confused, and then I tried to change the commit,
-> the link was re-added. I'm not sure if I need to properly test it first. Should I try it again with that markup-stuff, or should I just remove the link? It didn't seem to lead anywhere besides the page itself, but I can't tell if it is truly "broken" then, and if the markup-check would work.
Greetings!

The link should have led to an anchor (the # sign is used to identify text anchors .e.g headings)

Hello again, and thank you for your quick replies.

I think I broke that link, or it was already broken. After the sentence there is a sudden 1, and it doesn't lead me to any other header.

Here the link to the docs where it is for convenience:
https://devdocs.jabref.org/teaching#Ayaankazerouni

Apologies for the inconvenience.
Greetings.

Ah now I understand it. It's supposed to be a footnote link. If you scroll down to the References section. You see the 1 again.

The problem seems to be that gitbook doesn't support them https://gitbook.canny.io/feature-requests/p/footnotes
So it seems like the 1 should refer to the 1 at the bottom.
