@JostMigenda I've updated the cheat sheet here to include the lesson QR code. I think this completes everything needed from our side, so I will request @mine-cetinkaya-rundel to review it now.

If there is anything missing that you spot, please feel free to tag me. Thanks!

Thanks for adding this @SaranjeetKaur!

Can you double-check the PNG version, though? It looks a bit squashed horizontally, as if the export used the wrong pixel dimensions.

[SaranjeetKaur]

@JostMigenda Yes, I have reduced the dimensions for the png version as they ask for 1100 X 850 in the PR instructions:

Included a PNG file of the first page size 1100 x 850 in the pngs folder (for the website thumbnail)

Ah, I see; thanks for the explanation! The squashing looks okay for the main content and a bit awkward for the QR code (which is now no longer square); but if it’s just used as a thumbnail, that’s probably alright.

@JostMigenda (sorry for tagging you several times across PRs!)
From what I tested locally, the png would just be a thumbnail on this website and the downloadable version would be the pdf one (the pdf has the square QR code and the text on it should also be readable). Here's a screenshot of the local preview (top right has the "Download PDF" and the png is just below it):
