Hi! Foam author here. We generate markdown references to bridge [[wiki-link]]s to work with Markdown tools. For the time being this is optimised for a) the editing experience in VS Code and b) the GitHub pages publishing pipeline, so it's more convenient to generate markdown links without the `.md` suffix.
See bottom of the file here for example: https://raw.githubusercontent.com/foambubble/foam/master/rea...
This means that for the time being links are broken in the GitHub markdown preview.
I'll look into getting this fixed, but not sure what the best way forward is.
