I can't work out how to embed a video here, but the video at https://youtu.be/lvl8zVZ8glY should be attached to this entry

@nyalldawson example at line 16 doesn't work?

[nyalldawson]

@DelazJ Ah, I'll try, thanks!

I'll be in the train to Vienna this evening, and will try to do this (in case this issue is still here). (I'll also add the splash screen to it https://github.com/qgis/QGIS-Website/issues/1198)

[rduivenvoorde]

I've added Harrissou's comment, added the Youtube video and gave the attribution/credits to Martin and Nyall.

See: https://github.com/qgis/QGIS-Website/commit/fb777ede06b54d3cff599db44c2e6e6791311c49

So closing this one, please fix if needed.
