You might want to use one of the nice buttons we Ken has designed ;-)

Yould we pull this directly from the AppStream metainfo files? I am
worried that otherwise we will have yet another place where the IDs
need to be kept in sync (not that they should change or are even
likely to change, but ID changes might happen).

If stuff is published on Google's Play Store or Apples AppStore or
whatever Windows uses, adding links to that would be useful, I assume.
Thank you for working on the AppStream links!
